How can you calculate class interval?
Class interval refers to the numerical width of any class in a particular distribution. It is defined as the difference between the upper-class limit and the lower class limit.
Class Interval = Upper-Class limit – Lower class limit.
In statistics, the data is arranged into different classes and the width of such class is called class interval.
Class Interval exercise to try
The following data are weights of people on a diet
plan;
{52, 75, 92, 101, 83, 68, 133, 78, 104, 61, 39, 46, 135, 87,
131, 99, 104, 86, 67, 116, 89, 57, 87, 98, 131, 116, 135, 93}
a) With a class interval of 14, determine how many classes you get
b) Presents these weights by use of a frequency distribution table
Did you figure it out? Let us know in the comments
The platform that connects tutors and students
(A) The classes are supposed to be 7 with class interval 14 from 38.
(B) The classes should be as follows;
38-52
52-66
66-80
80-94
94-108
108-122
122-136
The upper limits are included while the lower limits are not included in the respective intervals.
Given a data set of 75 data values has 109 as the highest value and 29 as the lowest value, construct the class interval, showing the class limits of all the classes
Need of help house can someone plz help with this question below
1.state the number of class
2.how many student do we have from the table .
3.what is the class width.
4.calculate the lower and the upper class boundary for the seventh class.
