cumulative frequency charts

A plot of the cumulative frequency against the upper class boundary with the points joined by line segments. Any continuous cumulative frequency curve, including a cumulative frequency polygon, is called an ogive. There are two ways ..

Cumulative Frequency Distribution - Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interval. This is explained by an example below. The following ..

There are two ways of constructing an ogive or cumulative frequency curve. (Ogive is pronounced as O-jive). The curve is usually of 'S' shape. We illustrate both methods by examples given below: Draw a 'less than' ogive curve for the following dat..

The cumulative frequency for the distribution of the distance (in miles) that 20 randomly selected runners ran during a week is given in the ogive. Find the interquartile range for the data by constructing a box plot. => 18.5, Figure 2 or 11.2, Figure 2 or 23.5, Figure 1 or 12, ..

Which of the following statement(s) is/are true? I. On a pareto chart, the frequencies should be represented on the y - axis. II. In a frequency distribution, the number of classes should be between 5 and 20. III. The three types of frequency distributions ar..

Which of the following statement(s) is/are true? I. The other name for an ogive is a frequency polygon. II. The boundaries for the class limits 8.6 - 8.8 are 8.55 - 8.85. III. A Pareto chart can be used to show the relationship between the parts and the whole. => II only or I an..
