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 =
10
229
=22.9
Now, since no. of terms is even.
Therefore,
Median of given data =
2
(
2
n
)
th
term +(

+1)
th

16+23
=

39
=19.5
Since 25 has occured most frequently in the given set of data.
Therefore,
Mode of data =25

Answer:
(b)21
Step-by-step explanation:
formula to find median= (n+1)÷2
number of terms=12
therefore,the terms' ascending order would be
16,17,19,20,20,21,21,23,23,23,24,25
middle terms=21,21
⇒21+21 ÷ 2 (find the average)
⇒42÷2
⇒21
∴the median is 21.
