The following table shows the distribution of the heights of a group of students:

Use a graph sheet to draw an Ogive for the distribution. Use the Ogive to find:
the inter quartile range

The following table shows the distribution of the heights of a group of students: Use a graph sheet to draw an Ogive for the distribution. Use the Ogive to find: the number of students whose height is more than 168 cm

The following table shows the distribution of the heights of a group of students: Use a graph sheet to draw an Ogive for the distribution. Use the Ogive to find: the number of students whose height is less than 148 cm.

The following table shows the frequency distribution of heights of 50 boys: Find the mode of heights

The following table shows the distribution of heights of a group of factory workers. Determine the cumulative frequencies.

Draw an ogive for the following distribution Use the ogive drawn to determine: the median income,

The following table shows the distribution of the heights of a group of factory workers : Draw the 'less than' cumulative frequency curve on graph paper . Use 2 cm = 5 cm height on one axis and 2 cm = 10 workers on the other {:(" Ht. (cm): ", 150- 155, 155-160, 160-165, 165-170, 170-175, 175-180, 180-185),(" No. of workers " ," "6, " "12, " "18, " "20, " "13, " "8, " "6):}

The following distributions represent the height of 160 studens of a class : Find the modal height

The following distribution represents the height of 160 students of a school. Draw an ogive for the given distribution taking 2 cm = 5 cm of height on one axis and 2 cm = 20 cm students on the other axis. Using the graph, determine. (i) The median height.

Use Graph paper for this question. A survey regarding height ( in cm) of 60 boys belonging to Class 10 of a school was conducted. The following data was recorded. Taking 2 cm = height of 10 cm along one axis and 2 cm = 10 boys along the other axis draw an ogive of the above distribution. Use the graph to estimate the following : (iii) if above 158 cm is considered as the tall boys of the class. Find the number of boys in the class who are tall.
