Question

Create a possible linear relationship between two variables that you would like to explore.

1.Define the relationship of interest and a data collection technique.

2.Determine the appropriate sample size and collect the data.

3.Perform the appropriate analysis to determine if there is a statistically significant linear relationship between the two variables. Describe the relationship in terms of strength and direction.

4.Construct a model of the relationship and evaluate the validity of that model.

(1=breakfast, 2=lunch, 3=dinner

there were 9 people tested with 27 samples all together)

I know I need to create an anova to test the sample of means since there are three means, breakfast, lunch and dinner.

Time of day glucose is taken Glucoselevel 1 85 1 87 1 150 1 100 1 100 1 90 1 70 1 72 1 75 2 70 2 85 2 143 2 100 2 121 2 92 2 66 2 70 2 69 3 75 3 80 3 140 3 92 3 130 3 83 3 70 3 68 3 67

Explanation / Answer

Result of data in Excel

Observe that p-value is very high

hence there is no evidence that there is any difference in glucose level in Breakfast,Lunch ,Dinner
