# Correlation and Simple Linear Regression - Amount of Minutes Read in a 10 Day Period

Take your data and arrange it in the order you collected it.

The amount of minutes that I have read in a 10 day period

20, 10, 17, 20, 60, 0, 30, 0, 0, 0

Count the total number of observations you have, and label this number N. Then create another set of data starting from one and increasing by one until you reach N. For example, if you have 10 observations, then your new set of data would be (1, 2, 3, 4, 5, 6, 7, 8, 9, 10). This set of data is called a time series. Run a regression using your original set of data as your dependent variable, and your time series as an independent variable. Use the simple regression calculation page to calculate your regression.

Write a detailed description reporting your results and any conclusions that can be reached with it.

#### Solution Preview

Since there are 10 observations, we have N=10. Thus, the time series is (1, 2, 3, 4, 5, 6, 7, 8, 9, 10). If we let x represent time and y represent the number of minutes per day you have read, then we have the following table of data:

x y

1 20

2 10
