Question

the scores in mathematics test out of 25 of 15 students are as follows 20 25 19 23 15 20 9 10 5 16 25 20 24 12 20 find the median and mode of this data are they same

Answer 1

The median and mode of this data they are not same....

Answer 2

Answer:

Mode is 20 and median is 19.5

Step-by-step explanation:

Mode

Mode is the value which repeats many times in given observations

20 repeats many times than compared to other observations

Median

To calculate it first arrange the given observations in ascending or descending order

I arranged in ascending order

After arranging the observations are like

5,9,10,12,15,16,19,20,20,20,20,24,25,25

Now cancel first and last till u will remain with last 1 or 2 observations

If no of observations is odd u will be left with 1 observation

If no of observations are even u will be left with 2 observations

In that case u should take mean of those 2 terms

Here i am left with 19,20

So mean of them is (19+20)÷2

39÷2

=19.5
