Question

Using the interactive tool, select the Market Research data and request a sample size of 37. Request a plot of the RateCurr variable a.

a. Select Overall Mean to see the deviation of the first data point from the sample mean. If you squared the size of this deviation, you would get the value of
b. Select Group Means to see the deviation of the first data point from the sample mean for its group. If you squared the size of this deviation, you would get the value of That is one piece of the Sum of Squares

Answer 1

To calculate the sum of squares in market research data, we calculate the deviation of each data point from the sample mean and square it. The requested plot helps in visualizing these deviations and their squares.

Step-by-step explanation:

To calculate the sum of squares, we need to first calculate the deviation of each data point from the sample mean. Squaring this deviation gives us the squared deviation. For the RateCurr variable, we can request a plot and select Overall Mean to see the deviation of the first data point from the sample mean. If we square the size of this deviation, we would get the value of b. Similarly, if we select Group Means, we can see the deviation of the first data point from the sample mean for its group. If we square the size of this deviation, we would get the value of the sum of squares.
