Question

Define class interval, upper limit and lower limit with example.​

Answer 1

Answer:

Class intervals (lengths) should be equal. Intervals such as 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, etc are desirable. example, in the class 15 - 20, the starting point, 15, is divisible by the interval, 5.

The lower class limit of a class is the smallest data value that can go into the class. The upper class limit of a class is the largest data value that can go into the class. Class limits have the same accuracy as the data values; the same number of decimal places as the data values.
