Question

Scattergram of X and Y values for 10 cases to check for linearity and direction of XY association:

AGE: IV

DAYS a month you PROCRASTINATE

19, 20

20, 25

21, 15

21, 14

23, 18

24, 12

26, 13

32, 6

34, 8

45, 2

Answer 1

x:- Age

Y:- Days a month you procrastinate

x	y
19	20
20	25
21	15
21	14
23	18
24	12
26	13
32	6
34	8
45	2

From the above scatter plot we can see that the linear relationship between the two variables.the points are near to the straight line.

As values in age increases the values of days a month you procrastinate get decreased.

So it negative correlation.

So there is a linear & negative direction(opposite) correlation between age & days a month you procrastinate.
