Question 1

column graphs

Answer 1

-used to display results from experimental research(the IV and DV are plotted)
-bars are oriented vertically
-there are gaps between each bar
-bars used to compare different categories of data
-data is discrete

Question 2

bar graph

Answer 2

-display results from experimental research (the IV and DV are plotted)
-bars are oriented horizontilly
-there are gaps between each bar
bars are used to compare different categories of data
-data is discret

Question 3

line graph

Answer 3

-used to display reults from experimental research (IV and DV are plotted)
-both variables are either increasing or decreasing at regular increments
-almost always used to show change over time
-data is continous for both variables

Question 4

histogram

Answer 4

-used to display frequency distributions
-class intervals are on the horizontal axis, frequency in on the vertical axis
