In this video, you will learn the basics of line and dot plots
How are line plots different than dot plots?
Line plots use x's higher than the numbers showing the amount
for each number, whereas Dot plots use dots showing the
amounts above each quantity on lots line.
Let’s look at a good example.
Hayden surveyed 20 college students about the quantity of calls they made
in a 24 hour period. His details are as follows:
Number of calls made in 24 hour period.
4, 3, 4, 5, 0, 2, 4, 4, 5, 9, 4, 5, 4, 1, 0, 5, 3, 3, 5, 6
1) Find the minimum amount (least) and the utmost (greatest) values.
MINIMUM = 0 MAXIMUM = 9
2) Draw a line from the minimum amount to the maximum.
3) Draw a DOT or X on the number line showing each observation.
Cross off the number as you plot them.
4) LABEL the number line to show what being counted.
5) Supply the dot plot (or series plot) a TITLE.
