Answer to Problem 26SR

The central tendency median is best to summarise the test scores.

Explanation of Solution

Given:

  97,99,95,89,99,100,87,85,89,92,96,95,60,97,85

Calculation:

The given data is 97,99,95,89,99,100,87,85,89,92,96,95,60,97,85

Find mean, medina and mode of this data.

  mean=Sum of observationsNumber of observtions=97+99+95+89+99+100+87+85+89+92+96+95+60+97+8515=136515=91

In order to find the median arrange this data in numeric order

  60, 85, 85, 87, 89, 89, 92, 95, 95, 96, 97, 97, 99, 99, 100

The number of data is 15 which is odd.

So, median of the set of the data is the middle value which is 95

Hence, median is 95

Now, mode is the number which appears most in the data set.

So, the mode for the given set of data is {97,99,95,89,85}

Among the mean, median and mode, the least is mean.

And among mode and median, we can give preference to median.

Therefore, the central tendency median is best to summarise the test scores.
