Objective: Explain basics of statistics, how to draw a histogram
Subtopics to be covered:
- Revise basic concepts - data, observation, range, frequency, class intervals
- Construct frequency distribution table for exclusive and inclusive class intervals.
- Draw histogram for the given frequency distribution.
- Define mean, median and mode
- Calculate mean, median, mode for grouped and un-grouped data.
Learning Outcome:
- Students know the basics terms used in statistics
- They can read data and find the value for required terms
- They can draw a histogram for given data
- They can calculate mean, median, mode for a given data

1. Make a measuring scale on a wall till 180 cm. Measure the height of every student in your class on that scale.
Group students with same height. Make a table of length and number of students with same height (eg: 100 cm, 110 cm 120 cm…)
Find the range, mean and median of your class height.
Also, make a frequency table with class interval of 10 cm and make a fresh table of the data collected. Make a bar graph of this data and show the height of your class on a chart paper.
2. Collect last week's attendance attendance from your class. Make a table of how many students were present on the 6 days. (Monday, Tuesday, .... ). Check what is the average attendance of the class for the week
Draw a bar chart if you can on the attendance
