Answer 2

Answer:

Given

Data = 5, 10, 10, 12, 15, 13, 19

To find

The mean of the following data

Solution

Data = 5, 10, 10, 12, 15, 13, 19

$\green{mean = \frac{sum \: of \: all \: observation}{number \: of \: observation} }$

sum = 84

number of observation = 7

Now,

$\pink{ \frac{84}{7} = 12}$

Mode = 12

Observation is odd in number (7)

Therefore, Median = middle most observation that's is the 4th one

Median = 12

Mean = Median = Mode = 12
