Essays on Dependent Variable

1) Theories are to concepts as hypotheses are to variables. Hypotheses depend on tests that suggest multiple variables. On the other hand, theories are made up of concepts ("Theory and Practice of Social Research" 4). 2) Does a hypothesis propose a relationship between dimensions or variables? Yes. A hypothesis depends on the link that exists between two or several variables. Whereby, a slight change in variable ‘A,' leads to a change in variable ‘B.' In this case, it can be almost predictable that if the first event occurs on the first variable, then we expect variable ‘B' to ...

Question #1

The coefficient of determination (R-squared) shows the proportion of variance in the dependent variable, which is explained by the independent variable. Let’s say, the independent variable is the amount of money invested by a population of investors and the dependent variable is their profits received. Assume, the R-squared between the variables is 0.8567. This means that approximately 85.67% of the variance of profit received is explained by the amount of invested money.

Question #2

This phrase means that if the coefficient of correlation shows a strong relationship between the variables, it not always mean that there is a real causal ...

Abstract

This paper explores how research methodologies can be used to resolve organizational issues. Using Starbucks as the company of focus, this paper discusses the qualities of qualitative and quantitative research and how they can be used for investigation and analysis in an organizational setting. It is hypothesized, for instance, that the decline in Starbucks’ sales as well as the poor performance of some of its stores is due to poor customer service. The concept of customer service, however, is too abstract to measure directly. However, this hypothesis can be determined using qualitative research methods as opposed to the quantitative ...

Abstract

Linear Regression (LR) forecasts the value of a random variable (dependent variable) for a given value of an associated independent variable. The regression equation provides the formula for such a calculation. Simple Exponential Smoothing (SES) forecasts the bases its forecasts on a weighted average of past data, with more weight on the more recent periods. A smoothing factor helps in providing weight. It generally forecasts for the short-term. In the present case, we forecast the sales data for year-2 for ABC Furniture Company using both the methods. For SES, we use two smoothing factors α equal to 0.15 and 0.90 ...

Question

In all the programs the company chose to vary the amount of information shared with the workers of different stores considered.

In the program I and IV the independent variables are sick leave and absence.

In program III and IV, inventory and sales are partly dependent variable. It is expectable that increasing sick leave and absences result in declining sales. However, the sales made by the store will also depend on the demand for the products sold and customers’ purchasing power (income). The monthly staff time costs and weekly profits made are dependent variable i.e. their size depends on the performance management system implemented.

Question 2

There are other outcomes that can be measured. They ...

Abstract

Regression analysis estimates the value of a random variable (dependent variable) for a given value of an associated independent variable.

Introduction

The members of the LGBT community continue to suffer discrimination all over the world. Interestingly, the level of discrimination varies greatly from one nation to another. For example, Western Nations are more tolerant to homosexuality compared to Middle Eastern Nations, in general. Such variation in the level of discrimination suggests that there are governing factors that determine the perception of people towards homosexuality, making it an interesting topic in psychology. In order to fully understand how the perceptions of people towards homosexuality vary, it is important to set some variables and study them. There have been diverse studies performed ...

Discussion

The concept of the correlation coefficient is crystal clear to me. I have understood that the value of correlation coefficient ranges from -1 to 1. The relationship between the variables increases as the value moves away from zero. However, the movement in the negative direction indicates an increase in negative relationship and movement in the positive direction indicates increased positive relationship between the variables. In a case of negative correlation, an increase in the independent variable leads to decrease in the dependent variable. On the other hand, in positive correlation, an increase in independent variable leads to increase independent ...

Graphical analysis provides a visual presentation of data (Terpening, 2011). The authors use boxplot for the graphical analysis. Box plots are used to show differences in the means as well as the dispersion for different groups (Rubin, 2012). In the study, the boxplots show the concentration of various mineral across the different location as well as the dispersion of the concentration for each group. The important features are the dispersion measures and central tendency measures. Dispersion is shown by range while the central tendency is shown by mean (Jackson, 2012). The graphs clearly show the means and ...

There has been a reason for outrage as police brutality has escalated and many incidents have become more visible in communities today although was also present in years past. For example, according to Darden and Thomas, “If African Americans in Detroit between 1925 and 1945 were to name the worst racial abuses they had to encounter, without a moment’s hesitation they would have said “white police brutality” (Darden and Thomas 29). This has helped to encourage reporting of police brutality. But, citizens like Victor Rios who have experienced police brutality filed complaints and was simply ignored (Rios 59). ...

Focusing solely on the map and two graphs that contain data for Colorado, the most feasible research proposal to develop would be one that answers the question “is there a correlation between health, level of income, and the prevalence of cardiovascular disease among various population based on income groups in Colorado”. When developing a research question, narrowing it down based on several criteria is among the hardest steps to accomplish. However, this was made easier in this case thanks to the defined availability of data. So far, three groups of data were already available and so the most sensible ...

One of my research study hypotheses is as follows: when compared to other types of interventions, the Picture Exchange Communication System (SPECS) is significantly more effective at promoting functional communication between individuals. The null hypothesis (Hₒ) states that there is no statistically significant difference between SPECS, and other types of interventions, with respect to the efficacy of promoting functional communication between individuals.

Independent Variable and Dependent Variable

The current study seeks to assess the efficacy of PECS in the treating non-verbal individuals who suffer from autism. Specifically, the study seeks to compare effectiveness of PECS in promoting functional communication compared to the conventional methods for persons with autism. It also seeks to assess the conditions under which PECS is effective. Lastly, it seeks to compare the success rate of conversational speech between those who start using PEC at an early age and those who adopt at a later stage in life. Therefore, the independent variables are the educational program adopted (PECS and conventional teaching program), environmental ...

The research hypothesis: H1: In comparison with other types of interventions, PECS is the most effective in promoting functional communication for individuals with autism. The Null hypothesis (Ho) is usually the opposite of the alternative hypothesis H1, it is the hypothesis that the research wants to disprove or nullify (Whittaker, 2012). Therefore, the null usually refers to the common view of something. The null hypothesis is used in statistics to indicate that no variation exists between the stated variables (Gravetter & Wallnau, 2004). For this research, the null hypothesis is as stated below.

Ho: There is no difference between PECS and other types of interventions in promoting functional communication for individuals with autism

Abstract

The study uses the Posner paradigm to determine whether the condition of the cue can affect the reaction time of the subject. Most importantly is that the eye movement was prohibited. Using the data of 143 subjects, the ANOVA method and Bonferroni corrections, we have found out that the condition does influence the reaction time, however the difference between the cues is not significant Nonetheless the reaction time was far off from the target 100 ms due to inexperience and not understanding of the task set before the subjects. The results of the study have shown us two processes ...

Shopping is one of the most important parts in our daily life. We, as consumers, shop almost every day, whether it is a quick stop to the seven-eleven down the corner, or a family shopping in a large store like Wal-Mart at the weekend. From our perspective, when we plan to shop, all we want to consider is what we are getting and how much those items cost. On the other hand, as the suppliers in the shopping chain, the owners or investors of the stores have much more to consider when, where or even which kind of store ...

Research variable is the fundamental building blocks of research. It is the basis for a research hypothesis. A research study examines the relationship of a research variable in a particular context. A variable can be defined as anything that takes different values. The same applies to research variables as well. In research, variables are observable characteristic of an event or object. They can take one or more values. The common characteristic of all variable is that they do not have a fixed value. A research variable should have three characteristic features: it should be defined, it should have a ...

Hypothesis and Methodology

The proposed research paper will focus on the social psychology, specifically on the topic of how deep voices can influence an individual’s perception of another person (i.e. the speaker). This can be assessed in both public and private and formal and informal settings. The rationale behind the decision of choosing this topic is the fact that society puts a lot of weight into figures of authority. It is commonly perceived that the deeper a person’s voice is, the more authoritarian that person is. In some cases, the depth of voice is associated with personality types (i.e. how ...

The research question chosen for this paper is the determination of the existence of a relationship between the type of therapeutic intervention and self-harming behaviors in adolescent girls. The author of this paper has hypothesized that there is indeed a correlation between the type of therapeutic intervention and the resulting self-harming behaviors among adolescent girls. This means that adolescent girls receiving a certain therapeutic intervention will display a more significant decrease in self-harming behaviors as opposed to adolescent girls who do not receive a therapeutic intervention. For the null, hypothesis, it would basically suggest that there is no correlation ...

In research conducted by Rauscher, Shaw, and Ky (1993), the result of listening to music composed by the musician Mozart was an short-term improvement in tasks associated with spatial-temporal reasoning. The researchers hypothesized that higher brain functions correlate with music cognition. Dubbed the “Mozart Effect” by Dr. Alfred Tomatis, subsequent experiments differed on whether the influence is significant. While some studies support the proposed impact (Ivanov & Geake, 2003; Rauscher, Robinson, and Jens, 1998; Rideout & Laubach, 1996), others do not (Chabris, 1999; Mehr, Schachner, Katz, & Spelke, 2013; Steele, Bass, & Crook, 1999).

Abstract

In this case, we illustrate the application of multiple regression in economics. We gather data on the unemployment rate (dependent variable) and three independent variables; GDP per capita, maximum weekly unemployment benefit and population estimate for 2015. The data is collected from 39 different states. Regression analysis results show that there is a positive association between the unemployment rate and GDP per capita and population estimate. The relationship between unemployment rate and maximum weekly benefits is inverse. The evaluation of the reliability of the first-order model shows that it has a small coefficient of determination. The first-order model is ...

This paper is a critical review of the journal The emergence of a social problem: Single-parent families in U.S. popular magazines and social science journals, 1900 – 1998 that was authored by Margaret Usdansky. The sponsor of the research was partly supported by the National Science Foundation grant. The study was based on five hypotheses. The first hypothesis talks of newsworthy contemporary issues being inversely proportional to the quantity of discourse regarding single parent families (Usdansky, 2008). The second hypothesis touches on the nonexistent relationship between social science journal discourse and contemporary issues that are newsworthy. The third hypothesis talks ...

Abstract

Can female participation in the labor force contribute to economic growth? Is there a causal relationship between female participation in the labor force and economic growth? This paper addresses these questions using the vector error correction model. For this study, an annual time series data for the period 1970 to 2012 for the United States has been used. The results show that there exists a co-integration between female participation and GDP per capita, which is a proxy measure for economic development. The result does not support a two-way causality between the variables. However, a causality running from GDP per ...

Introduction

Prenatal iron supplementation has been the customary recommendation in addressing maternal anemia especially in developing countries for over thirty years (West, et al., 2014). There is paucity of information regarding the correspondence between hemoglobin levels in pregnant women and iron supplementation. The limited information in this pertinent public health issue is more pronounced in developing countries as West, et al., (2014) opines. The main purpose of this research is thus to establish the efficacy of prenatal iron supplements on the hemoglobin levels of pregnant women in developing countries.

Explain the difference between multiple independent variables and multiple levels of independent variables. Which is better?

It is important to note that design experiment requires researchers to decide on the type of dependent variable that they should use in their respective study and distinguish the same from the independent variables. However, every research ought to have a single dependent variable, but the independent variables can be many, an aspect that makes the independent variables be considered as parameters. Therefore, for our case, multiple independent variables indicate the use of many parameters in conducting a study. For example, if we take a survey to find the extent of obesity in a given area, and take the ...

The study sought to establish how the race of the defendant and the type crime that the individual commits affects the decisions that jurors make (Gordon et al., 191).
