Question
1.A Science instructor assigns a group of students toinvestigate the relationship between their grade point average andtheir consistncy in studying. The correlation between GPA andstudying consistency is 0.853. Assume that the relation is linear.Describe the association. a. Weak linear relation in a positive direction b. No evidence of relation c. Strong linear relation in a negative direction d. Strong linear relation in a positive direction e. Strong curved relation in a positive direction 2. In a school, a scientist observed children during lunchtime over several months to study how much they eat and for howmany minutes, He evaluated in calories what each child ate each dayfor lunch. After careful observations, he found that the variablestime and calories relate linearly, and that the correlation betweenthose variables is 0.633. Suppose he was to record time in hoursrather than in minutes. Would the correlation change? 1.A Science instructor assigns a group of students toinvestigate the relationship between their grade point average andtheir consistncy in studying.

1) d. Strong linear relation in a positive direction 2) No. Change will not occur. Correlation is not affected by changes in the center or scaleof either variable. Changing the units or baseline of eithervariable has no effect on the correlation coefficient.Related Questions
