Question

The frequency of the overlapping class-interval (40-60) from the following data:
31, 27, 15, 18,25,35, 37, 25, 40 30, 37, 32, 28, 29, 26, 39, 45 is:​

Answer 1

Answer:

2

you just need to count how many nos. are there in the data between 40-60

here 40 is the lower limit and 60 is the upper limit and class interval is 40-60 and class size is 10 ( difference between upper and lower limit)

while counting the frequency of the class interval in the data, if the upper limit occurs, we do not count it. we count the upper limit in the next class interval where it becomes the lower limit.
