In a retail market, fruit vendors were selling oranges kept in packing baskets. These baskets contained varying number of oranges. The following was the distribution of oranges.
Number of oranges 10-14 15–19 20-24 25-29 30–34
Number of baskets 15 110 135 115 25
Find the mean number of oranges kept in each basket. Which method of finding the mean did you choose?

Mean = 22 + ( 25/400 ) × 5
= 22 + 5/16
= 22 + 0.31
= 22.31
Therefore ,
mean = 22.31
[ Here , we used we used Step deviation
method to find the mean because xi and
fi are numerically large numbers ]
I hope this helps you.
