I don’t understand standard deviation and outliers

Step-by-step explanation:

Standard Deviation is a measure of how spread out the numbers are in a data set. It's formula is square root of variance. To calculate variance:

Outliers are the number(s) in a data set that significantly contrast from the other data points. For example, in the data set: 1, 2, 3, 4, 10, the outlier is 10 because it's such a big jump compared to the other numbers.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
