Sana po makatulong at correct me if I'm wrong. Makiki-brainliest po kung nakatulong po ako.
Range: 14
Average/Mean Deviation: 4.5
Standard Deviation: 5
Variance: 25
First, find its range:
Range = maximum(xi) - minimum(xi)
where xi represents the set of values.
Average/Mean Deviation: (picture)
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values
Work out the average, or arithmetic mean, of the numbers:
Count: 8 (How many numbers)
Sum: 160 (All the numbers added up)
Mean:20(Arithmetic mean = Sum / Count)
Then, take each number, subtract the mean and square the result:
Differences:
-8, -7, -3, 2, 2, 3, 5, 6
(Every Number minus Mean)
Differences2:
64, 49, 9, 4, 4, 9, 25, 36
(Square of each difference)
Now calculate the Variance:
Sum of Differences2:200(Add up the Squared Differences)
Variance:25(Sum of Differences2 / Count)
Lastly, take the square root of the Variance:
Standard Deviation:5(The square root of the Variance)
