frequency distribution for a grouped frequency table

The number which tells us how many times a particular data appears is called the frequency. For example, 2 marks have been scored by five students which means marks 2 occurs five times. Therefore, the frequency of score 2 is five. Similarly, the frequency of mark..

A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is called an array. The difference between the great..

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 t..

In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in both directions to meet the X..

The scores of 20 students in a quiz are collected and shown in the table: Construct a frequency distribution and a histogram for the data. => Figure - A or Figure - B..

The frequency table displays the different age groups of employees in a company. How many employees are there in the age group of 40 - 49? => 6 or 5 or 4 or 7..

Pick an appropriate frequency table for the stem and leaf plot. => Figure 1 or Figure 2..

The histogram shows the number of students and their age groups in a school. Which interval has the lowest frequency? => 7 to 9 or 13 to 15 or 4 to 6 or 10 to 12..

Identify the incorrect statement. I. The histogram is a graph that displays the data by using continuous vertical bars of various heights to represent the frequencies of classes. II. The frequency polygon is a graph that displays the data by using lines that connect points plott..
