Frequently Asked Questions
What is the difference between a pictograph and a bar graph?
A pictograph uses pictures or symbols to represent data values, while a bar graph uses rectangular bars of different heights along an axis.
How do we draw tally marks for the number 7?
You draw four vertical lines and one diagonal line across them to make a group of five (IIII), and then two separate vertical lines next to it (II), making a total of 7.
Why do we need a 'key' or 'scale' in a bar graph or pictograph?
A scale tells us how many actual units are represented by one picture symbol or one unit length on the graph axis, making large numbers easy to draw.
