Activities
[Author - Kripa S]
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
