Question

Given the impact of television on children's attitudes andbehavior, an important concern of behavioral scientistis is theamount of time children of various ages spend watching T.V. Thefollwong data are the weekly viewing times (in hours) of 12 yearolds. Compute the mode, median, the mean, the range the sum ofsquares, the variance, and the standard deviation. 18   17   22   20  25   20   16 19   18   22  26    23   23 23 24   24   22   21 19   20 20 Given the impact of television on children's attitudes andbehavior, an important concern of behavioral scientistis is theamount of time children of various ages spend watching T.V.

Explanation / Answer

Mode= the most frequent number present in the data (which oneappears the most?)
Mean= the average= add all the numbers and divide by how manythere are
Median= how many numbers there are (n) + 1/(divided by)2
The Range= the highest number - the lowest
The Sum of Squares= square each number and add them allup
The Variance=   subtract the mean from eachscore (number), square each result ,   sum allthe squares, divide the sum of squares by n (how many numbersthere are).
The Standard Deviation= the square root of the variance
Hope this helps! :)
