A person has decided to construct a frequency distribution for a set of data containing
60 numbers. The lowest number is 23 and the highest number is 68. If 5 classes are
used, the approximate class width and range will be
09.45
07.46
O 11,45
0 8,46

Answer:
Class size is 5, with a maximum value of 44 and a minimum value of 0.
Range
=44−0
=44
Number of intervals = 5
44 = 9
Explanation:
A table displaying "classes" or "intervals" of data records with a count of the number of submissions in each class is known as a frequency distribution.
The quantity of data records in a class determines its frequency, f. The lowest and highest values in each class are referred to as the "lower class limit" and the "upper class limit," respectively.
The distance between both the bottom bounds of succeeding classes is known as the "class breadth." The range is the number of data entries between the maxima.
A line graph showing the frequency of each category now at upper class border is known as an ogive or cumulative quantitates. The cumulative frequency are indicated on the vertical axis, while the upper bounds are indicated on the horizontal axis.
