You will recall that in the L26 — A1 Assignment you created a bar graph.

In this activity, you will look at frequency distribution tables and  create bar graphs from these.

Let's say that you have gathered information from your classmates on their favourite school subject. You may have made a frequency table from that information that looks like this:

Favourite Subjects of Room 5 Students

Favourite Subject	Tally	Frequency
Computers	IIII	4
Science	II	2
Social Studies	IIIII III	8
Phys. Ed.	IIIII IIIII II	12
English	IIIII I	6
Math	IIIII IIIII III	13

From the information in the frequency table, you can build a bar graph. A bar graph from the above information could look like this:

Very quickly you can see from reading the bar graph that Math and Phys. Ed. are the favourite subjects of this group of students.
