Frequency
Relative frequency

Evidence Requirement:

2.2 Conduct a survey. Survey at least 10 institute students to find which activity they prefer to do in their free time. Use a frequency table for your data, you may use like the table below (PCs 1.4 and 2.2):

Preferred activity	Tally	Frequency	Relative frequency (%)
Reading story books
Watching TV
		Total =

2.3 Find therange of this data set. And which activity is preferred by most of the students other than playing

2.4 Draw a bargraph to illustrate the above data taking the scale of 1 unit length = 5 students
