For the next six month period Fred wants to calculate the monthly deviation from the average

Complete the chart to find the mean, variance, and standard deviation. Remember to use commas and round numbers to the nearest tenth

Use this data in the problem below. Follow the steps carefully. Round to the nearest tenth. Lot 3: Week 1:345 Week 2: 340. Week 4: 325

Step 1: Jim enters the data calculates the average or mean.

Step 2: Jim calculates the deviation from the mean by subtracting the
mean from each value.

Step 3: Jim squares each deviation to remove negative signs.

Step 4: Jim sums the squares of each deviation and divides by the
count for the variance.

Step 5: Jim takes the square root of the variance to find the standard
deviation.
