Activity 1&5: Calculating a Correlation Coefcient Is there a relationship between the number of pencils and the number of pens a student owns? Use the hypothetical data in Table 143.3 to nd out by calculating the Pearson r correlation coefcient: TABLE 113-3 FENCES VS. PENS \"II-- Name}!L Pencils [.33 Pens U 1. Multiply EXY by n: = 2. Multiply EX by EY = 3. Subtract step 2 from step 1: 4. Multiply BF by n: 5. Square EX: 6. Subtract step 5 ora step 4: T 3 _ Multiply BF by n: _ Square BY: 9. Subtract step 8 from step TI": lil. Multiply step ti by step 9: ll. Take the square root of step It} 12. Divide step 3 by step 11 [You should get .75] Now: what does this correlation {r} of .'?5 tell you? Explain briey
