cumulative frequency curve

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..

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interva..

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 frequency distribution table gives the marks o..

If the above graph is joined by a smooth curve, then it is known as a frequency curve..

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 among the following statement(s) is/are true about histograms? I. Midpoints are useful in determining class widths and class boundaries. II. Histograms are useful in displaying cumulative frequencies. III. Histograms are used to display categorical data. IV. Histograms are..

Two types of graphical representation of data are the histogram and the ogive. A histogram is a diagram which represents the class interval and frequency in the form of a rectangle. When the class intervals are unequal, each rectangle is constructed with the class interval as the ..
