4. It is assumed that achievement test scores should be correlated with student's classroom performance. One would expect that students who consistently perform well in the classroom (tests, quizzes, etc.) would also perform well on a standardized achievement test (0 - 100 with 100 indicating high achievement). A teacher decides to examine this hypothesis. At the end of the academic year, she computes a correlation between the students achievement test scores (she purposefully did not look at this data until after she submitted students grades) and the overall g.p.a. for each student computed over the entire year. The data for her class are provided below. Achievement G.P.A. 98 3.6 96 2.7 94 3.1 88 4 91 3.2 77 3 86 3.8 71 2.6 59 3 63 2.2 84 1.7 79 3.1 75 2.6 72 2.9 86 2.4 85 3.4 71 2.8 93 3.7 90 3.2 62 1.6 A. What is your computed answer? B. What does this statistic mean concerning the relationship between achievement and GRA?

Transcribed Image Text:4. It is assumed that achievement test scores should be
correlated with student's classroom performance. One
would expect that students who consistently perform well
in the classroom (tests, quizzes, etc.) would also perform
well on a standardized achievement test (0 - 100 with 100
indicating high achievement). A teacher decides to examine
this hypothesis. At the end of the academic year, she
computes a correlation between the students achievement
test scores (she purposefully did not look at this data until
after she submitted students grades) and the overall g.p.a.
for each student computed over the entire year. The data for
her class are provided below.
