a. Compute the mean, median, and mode.
b. Compute the variance, standard deviation, range, coefficient
of variation, and Z scores. Are there any outliers?
c. Are the data skewed? If so, how?
d. Based on the results of (a) through (c), what conclusions
can you reach concerning the total fat of chicken
Here is some info.
Find the mean first = sum of scores/number of scores
Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.
Standard deviation = square root of variance
I'll have to let you do the calculations.
