Scenario. A health psychologist conducted a study of the relation of number of hours exercised each week (as the predictor variable) and number of days sick per year. The results for four individuals studied were as follows.

DATA

Weekly Exercise Hours	Sick Days Per Year
5	6
4	7
0	10
8	5
10	3
2	4
1	8

1.The scale of measurement for the ONE variable is ___________.  

Select from Nominal, Ordinal, Interval, Ratio

2.The scale of measurement for the OTHER variable is ___________.

Select from Nominal, Ordinal, Interval, Ratio

3,Are the results of this study statistically significant? _________  

4.How would you write the results in a writeup? ____________________________

5. Show how the results are likely to be graphed

Answer 1

1] The scale of measurement for the weekly eercise hours variable is RATIO.

2] The scale of measurement for the Number of sick days variable is RATIO.

3] By using SPSS we have

Level of significance =0.05 (Assumed)

Correlation r between Weekly exercise hours and Sick days is -0.756

P value= 0.049

Since P value SMALLER than the level of significance therefore SIGNIFICANT .

4] From above analysis we can conclude that there is correlation between Weekly exercise hours and Sick days at 0.05 level of significnce

5] To graph this data we will use Scatter plot
