In the data set, what is the variance? 6 8 1 9 4

The variance is 8.24

Step-by-step explanation:

we have

set of data

step 1

Find the mean

Adds the values and divide by the number of values

step 2

for each number: subtract the Mean and square the result

step 3

work out the mean of those squared differences

----> this value is called the "Variance"

thats not a system of equations, that is a solution
