Question

Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers. If necessary, use / for the fraction bar(s).
What is the mean of the given distribution, and which type of skew does it exhibit?

{4.5, 3, 1, 2, 4, 3, 6, 4.5, 4, 5, 2, 1, 3, 4, 3, 2}

The mean of the distribution is
, and it exhibits a
skew.

Answer 1

Mean = 3.25

Solution:

Step 1 : Given data:

4.5, 3, 1, 2, 4, 3, 6, 4.5, 4, 5, 2, 1, 3, 4, 3, 2

Step 2:

Sum of the numbers

          = 4.5 + 3 + 1 + 2 + 4 + 3 + 6 + 4.5 + 4 + 5 + 2 + 1 + 3 + 4 + 3 + 2

          = 52

Sum of the numbers = 52

Number of terms = 16

Step 3:

$\text{Mean}=\frac{\text{Sum of the numbers}}{\text{Number of terms}}$

         $=\frac{52}{16}$

         = 3.25

Mean = 3.25

Mean of the distribution is 3.25.
