CORRELATIONS REPORT ASSIGNMENT

Correlations Report Assignment

Section I - Data File Description

In this assignment, we calculate correlation coefficients and provide interpretations for them using the terminology we have learned in this course. However, we will be examining the simple association between these two variables.

First of all I create a correlation matrix for all of the variables in the spreadsheet. Examine the correlation coefficients for IQ and all other variables. I will Identify the single lowest correlation coefficient (not significant) and the highest correlation coefficient for IQ and these other variables. We also, create a scatterplot for IQ and the one other variable (Variable X) that it is most highly correlated within this sample.

Variable Codes

•ADDSC - The average of the three ADD-like behavior scores obtained in elementary school.

•SEX - 1 = male; 2 = female.

•REPEAT - 1 = repeated at least one grade; 0 = did not repeat a grade.

•IQ - IQ obtained from a group-administered IQ test.

•ENGL - grade of English in ninth degree: 1 = college prep; 2 = general; 3 = remedial.

•ENGG - Grade in English in ninth grade: 4 = A; 3 = B; and so on.

•GPA - Grade point average in ninth grade.

Sample size

The sample size for this data is 88 and there is not any missing value in the data set.

Section II - Assumptions, Data Screening, and Verification of Assumptions

Acoefficient of association is a mathematical assess of how much one number (such as a share price) can anticipated to be leveraged by alterations in another (such as an index). It is nearly associated to covariance.



A correlation coefficient of 1 entails that the two figures are flawlessly correlated: if one develops so does the other, and the change in one is a multiple of the ...
