Find the following statistics:
a) =
b) IQR =
c) Is or the appropriate measure of standard deviation? Explain why.

d) What is the standard deviation? Be sure to report this number using the proper symbol.

e) In context, interpret the standard deviation value in part d).

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
