Bar Graphs

A bar graph is a chart or graphical representation of data. A bar chart, also known as a bar graph, is a graph or chart that displays categorical data using rectangular bars with heights or lengths equal to the values they represent. Typically, bar graphs show categorical and numerical variables grouped in class intervals. A bar graph is useful for comparing and analyzing a set of data.

Student Learning Outcomes
• The student will calculate and construct the line of best fit between two variables.
• The student will evaluate the relationship between two variables to determine if that
relationship is significant.
Collect the Data
Survey ten textbooks. Collect bivariate data (number of pages in a textbook, the cost of the
textbook).
1. Complete the table.
Number of pages
Cost of textbook
Table 12.10
2. Which variable should be the dependent variable and which should be the independent
variable? Why?
3. Graph “pages" vs. "cost." Plot the points on the graph in Analyze the Data. Label both
axes with words. Scale both axes.
Analyze the Data
Enter your data into your calculator or computer. Write the linear equation, rounding to four
decimal places.
1. Calculate the following:
a. a =
b. b
c. correlation
%D
d. n =
e. equation: y = ,
f. Is the correlation significant? Why or why not? (Answer in complete sentences.)

Lab 12.1
1. For Lab 12.1, use the following table to determine if there is a correlation between the price of a text
