# Mean, Median, Mode and Standard Deviaton

1. Suppose you have administered a test of manual dexterity to two groups of 10 semi-skilled workers. one of these two groups of workers will be employed by you to work in a ware house with many fragile items. the higher the manual dexterity of a worker the less likelyhood that worker wil break significant inventory.Because of a unique contract you must hire all 10 employees from one of the two groups and none from the other.

GROUP A= 98, 85, 30, 66, 99, 95, 57, 62, 99, 100

GROUP B= 64, 81, 62, 88, 82, 79, 90, 81, 85, 79

Decide wich group to choose? consider at least two measures of central tendancy and at least one measure of dispersion for each group and use those to make your choice.

2. Calculate the mean, median, mode for the data collected on the attachment. Also calculate the standard deviation.

Select a type of quantative data to collect from your own life. examples such as the # of people you see at work each 1/2 day, the # of call you get in the AM and in the PM or any other numeric data that you could split between AM and PM. Please divide the day in 2 parts Am and PM and get the data on ONE of your example for each part. in a brief paper explain the data you collected. please have about 20 observations (2 for each day) Provide a description of the data collected and a table with the data you have collected. I will use this data for the next math problems..

then refer to the measures of tendancy(mean ,median, mode) ARE THESE NUMBERS HIGHER OR LOWER THAT WHAT YOU EXPECTED? which of these measures of tendancy do you think most accurately describes the lifestyle variable you are looking at? Are you suprised at the number you have obtained from the standard deviation ?
