PSY 7864-PSY7864 Unit 6 Assignment 1 Running Head: UNIT 6 ASSIGNMENT 1 Unit 6 Assignment 1 Introduction Correlation is as easy as understanding that one thing may be an association with another, as it’s measured to analyze how precisely two variables relate. Through correlation a strong or weak relationship between variable can be seen (Warner el at, 2013). For this Unit’s assignment, a dataset will be analyzed to the assumptions of correlation for GPA and Final, as providing supporting details of the strengths and limitations of the correlational analysis. Section 1: Data File Description The dataset displays the relationship between gender, GPA, total and final grade. Gender can be categorized as female or male and is considered a nominal scale of measurement because of the nonexistence of intrinsic order (Warner el at, 2013).An interval scale on the scale of measurement can be viewed in the variables of GPA, total and final grade., in which, the GPA column represents the average value of the accumulated final grades earned for the courses, the Totals are described as total numers of points earned and the Final grade reflects the number of questions answered correctly on the final exam. For this dataset, the correlation used would be known as Pearson’s r since it is used to describe the strength of a linear relationship between two quantitative variables (Warner, 2013). When analyzing the interval scale dataset, some figures can be 2 Running Head: UNIT 6 ASSIGNMENT 1 determined. For example, the sample size of 105 students with a GPA ranging from 1.14 to 4.00.
