Answer 1

Answer:

3,25,28,25,16,23,17,22,25,25

Total no. of terms =10

Sum of data =23+25+28+25+16+23+17+22+25+25=229

Therefore,

Mean of given data =10229=22.9

Now, since no. of terms is even.

Therefore,

Median of given data =2(2n)th term +(2n+1)th term

=216+23=239=19.5

Since 25 has occured most frequently in the given set of data.

Therefore,

Mode of data =25
