Answer the following short questions regarding statistics and data analysis (a) If the correlation coefficient between DSE result and college GPA is 0.5, what is the effect size and its interpretation respectively? (b) What is the function of “introduction” and “discussion” in a research paper respectively? (c) Explain what is “parametric test”, “omnibus test” and “robust test” respectively? (d) By studying the following figure, decide whether there is any potential main effect(s) and an interaction effect, respectively. Provide evidence. (e) What does tobs = 3.47 mean? What does tcrit = 3.47 mean? (f) If the ƞ2 in an experiment is 0.6, give any possible value of ω2.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
