Given below is the frequency distribution of the heights of 50 students of a class: Class Interval:, 140-145, 145-150, 150-155, 155-160, 160-165 Frequency:, 8, 12, 18, 10, 5 Draw a histogram representing the above data.

A survery regrding the heights (in cm ) of 50 girls of a class conducted and the following data was obatained. Find the mean of above data.

Given below is a bar graph showing the heights of five mountain peaks. Read the bar graph carefully and answer the following questions: (i) Which is the highest peak and what is its height? (ii) What is the ratio of the heights of the highest peak and the next highest peak? (iii) Arrange the heights of the given peaks in descending order.

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 : (i) the median
