getting the class limit%3b frequency distribution 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..

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 ..

We shall now deduce the Poisson distribution from the binomial distribution by assuming that n and p 0 such that the product np always remains finite, say l . We shall now use a very important result of limits in Calcu..

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 ..

Identify the discrepancy in the frequency distribution. Class Frequency 15 - 19 2 19 - 23 3 23 - 27 1 27 - 31 6 31 - 35 4 => The class width should be more than 5 and it should be an odd number. or The class width should be more that 5, the classesh..

The daily sales of books in a book stall for 20 consecutive days are: 20 15 32 18 40 9 12 19 22 28 31 54 42 39 45 16 60 38 44 25 Find the class limit in which the sales are maximum by constructing a frequency distribution table with 5 classes..

The frequency table represents the number of employees and their salaries. Find the difference between the number of employees getting a salary of $4200 and $3900. Salary ($) Frequency 3900 8 4000 5 4100 4 4200 10 4300 6 => 1 or 2 or 3 or 6..

On the annual day function of a school, chocolates were bought to be distributed among the students of 6, 7, 8 and 9 grades. The frequency table shows the number of chocolates that were distributed among the students of different grades. How many chocolates d..

On the annual day function of a school, 200 chocolates were brought to be distributed among the students of 6 th , 7 th , 8 th and 9 th grades. The frequency table shows the number of chocolates that were distributed among the students of different grades. Ho..
