Question

Here is the hair length of a sample of 10 students:

15, 4, 14, 1.5, 22, 2, 16, 19, 18, 3

What is the mean, median, mode, standard deviation, Q1, Q3 and IQR? Make sure you answer every part and label each. No need to show work. Round any numbers to the tenths place.

Answer 1

Answer:

The answer to your question is below

Step-by-step explanation:

Mean

           (15 + 4 + 14+ 1.5 + 22 + 2 + 16 + 19 + 18 + 3) / 10

         = 114.5/10

         = 11.45

Median

           1.5 , 2, 3, 4, 14, 15, 16, 18, 19, 22

           (14 + 15) / 2

          = 14.5

Mode

          There is no mode

Standard deviation

  Formula

                         $\sqrt{\frac{(x - xm)^{2}}{n - 1}}$

Standard deviation = 7.5
