In a mathematics test given to `15` student , the following makes ( out of `100`) are recorded :
`52,60,42,40,98,52,48,39,41,62,46,52,54,40,96`
find the mean, median and mode of the given data

Explanation

Mean = `( " sum of the given observations ")/(" total number of obsevations ")`
` 822/15= 274/5 = 54.8`
Now, we arrange the given data in an ascending order, as under
`39,40,40,41,42,46,48,52,52,52,54,60,62,96,98 `
In this data, the most occurring item is `52.` ltbr. Mode `= 52`
Total number of terms = `15 `(odd)
median= makes obtained by `( (15+1)/2)` th student
= marks obtained by `8th ` student = `52`
Mean `= 54.8` median `= 52` and mode `= 52 .`
