Make a cumulative frequency (less than type) table and draw a o give from the give data.

Make a cumulative frequency distribution (greater than type) table and draw an ogive.

Make a cumulative freqency distribution table from the given data and draw a ogive.

In a frequency distribution having 6 class intervals the total frequency is 100 and cumulative frequency less than type and cumulative frequency more than type corresponding to the fourth class interval are 86 and 50 respectively. Find the frequency of the fourth class interval.

Given that the cumulative frequencies of less than type and more than type corresponding to a class interval are 320 and 323 respectively, when the total frequency is 500, find the percentage of the class-interval.

Draw an ogiove (less than type) from the given data.

Name the wave whose frequency is less than 20 Hz.

Draw an ogiven (less than type) from following data.

From the frequency distibution table given below draw a less than ogive.

If f_i, F_i, F'_i are respectively the frequency less than type cumulative frequency, greater than type cumulative frequency of i-th class and N be the total freqnency then which of the following is correct?

Draw the o give (both greater than type and less than type) from the given frequency distribution table and from it find the median.
