Given the following raw scores, calculate the following values, show your calculations:
Describe each of the following statistical terms, and where applicable, define with the appropriate equation:
a. Range _______________________________________________
b. Variance _____________________________________________
c. Standard Deviation ______________________________________
For more details see the attached file.
a) Range: Largest - Smallest = 9 - 3 = 6
b) Variance = (Sum of the squares of the observations/ No. of observations) - ( Mean)2,
Where Mean = Sum of the observations / No. of observations
Sum = 77
Mean = ...
The expert describes the range, variance, standard deviation and calculate values.
