The following table shows the distribution of salaries of a group of workers :

Determine cumulative frequencies
Draw the cumulative frequency curve i.e. less than ogive on a graph paper.
From graphs, write down the median salary (in Rs)?

On the basis of the following frequency distribution draw less than cumulative frequency curve.

Draw ‘less than’ cumulative frequency curve on the basis of following distribution :

Draw the less than cumulative frequency graph for he following data :

Determine median-value of the following series using graphic method : (i.e., By less than ogive, By more than ogive approach)

The following table gives the distribution of students of two sections according to the marks obtained by them : : Represent the marks of the students of both the sections on the same graph by two frequency polygons. From the two polygons compare the performance of the twosections.

Draw the less than cummulative frequency graph for the following distribution giving 300 telephone calls according to the duration in seconds.

Height of 50 plants in a garden were recorded and data is presented as below: Draw ‘less than’ ogive and ‘more than’ ogive simultaneously on the same graph and find the median of the data from graph. Also verify your result by using formula.

During the medial check up of 35 students of a class, their weights were recorded as follows: Draw a less than type ogive for the given data. Hence obtain the median weight from the graph and verify the result by using the formula.

The shoppers who come to a departmental store are marked as: man (M), woman (W), boy (B) or girl (G). The following list gives the shoppers who came during the first hour in the morning: W W W G B W W M G G M M W W W W G B M W B G G M W W M M W W W M W B W G M W W W W G W M M W W M W G W M G W M M B G G W Make a frequency distribution table using tally marks. Draw a bar graph to illustrate it.
