interest in the data is the variability of the values. According to the parameters of this data the coefficient of variability is 22%. The graph is right skewed‚ as we see the mean (5000) is right to the median (4875)‚ and the median is right to the mode (4000); its peak represents the most likely value (4000). According to the input the total demand average generated for this region is 5000 jackets. For the Region 2 the demand is generated from (2000‚ 4000‚ 5000) with a mean of 3667. One point

Calculate the mean‚ median‚ and mode for your data as a whole. 8. Now calculate the mean‚ median‚ and mode of each of your classes or groups. 9. Indicate which measure of central tendency best describes your data and why. Then compare your results for each class or group‚ and point out any interesting results or unusual

| The mean is the average of all of the numbers added together and divided by the number of data. The median is the middle number in a data set that is numerically in order. The mode is the number that occurs the most often in a data set. A skewed distribution measures lack of similarity in a bell-shaped graph known as a bell curve. It occurs when data is plotted on the graph based on normal measured traits.

Activity 2.1.2 Student Response Sheet Part I: Answers Example 1: Prosthetic‚ Inc. and Orthotics and Prosthetics had almost identical profit increases between the years 1998 and 2009. The yaxis on Orthotics and Prosthetics’ graph has been altered to have a larger range than the range used for the yaxis on Prosthetic‚ Inc.’s graph. If the same range was used for both graphs‚ they would look as follows: Example 2: ABC.com presented that the average blood sugar level before meals for Americans is 142 mg/dL

Measures of Central Tendency 1. What Do You Mean by Mean? a) The mean of the salaries is calculated by adding up each individual salary and dividing it by the seven employees. The mean of the seven salaries is $43‚814.29. The mean compares to the individual salaries because it shows the average of all the salaries together. The employees would use the average to negotiate with Dick for a higher salary‚ because by looking at the average you can see that Dick’s salary is an outlier compared to
