Answer 2

Given,

The following set of observations: $15, 22, 18, 27, 31, 21, 14, 36, 25$ and $34$

To find,

The mean and median of the given observations.

Solution,

The mean and median of $15, 22, 18, 27, 31, 21, 14, 36, 25$ and $34$ will be $24.3$and $26$ respectively.

We can easily solve this problem by following the given steps.

We know that the following formula is used to find the mean of given observations:

Mean = Sum of all observations/total number of observations

The total number of observations is $10$.

Mean $= (15+22+18+27+31+21+14+36+25+34)/10$

Mean $= 243/10$

Mean = $24.3$

Now, the median is the middle term of the observation. If the number of observations is odd then it is the middle term and if it is even then the sum of the two middle terms is divided by $2$.

In this case, the number of observations is $10$ (even).

Now, the two middle terms will be the $5$th and $6$th observations.

Middle terms = $31$ and $21$

Median $= (31+21)/2$

Median $= 52/2$

Median $= 26$

Hence, the mean and median of $15, 22, 18, 27, 31, 21, 14, 36, 25$ and $34$ is $24.3$ and $26$ respectively.
