Analyzing Data with Line Graphs

What was the reason for skipping Lesson 9.3?

• It involved complex calculations.

• It was a hands-on activity not suitable for video.

• It was not important.

• It was fully theoretical.

What does a line graph primarily show?

• Categorical data comparisons

• Correlations between two variables

• Data distribution

• Changes in data over time

What should be equal in a line graph's scale intervals?

• The graph lines

• The distances between values

• The data points

• The labels

Why might a break in the scale be necessary on a line graph?

• To confuse the viewer

• To highlight data anomalies

• To fit the graph better visually

• To emphasize certain data points

What is the purpose of ordered pairs in a line graph?

• To confuse the data representation

• To represent data points accurately

• To make the graph look full

• To reduce the accuracy of the graph

What does the vertical axis typically represent in a line graph?

• Data categories

• Numerical values

• Temperature changes

• Time of day

What time showed the greatest temperature drop?

• From 4 AM to 5 AM

• From 3 AM to 4 AM

• From 2 AM to 3 AM

• From 1 AM to 2 AM

How does the temperature change from 5 AM to 6 AM?

• It increases

• It decreases

• It stays the same

• It fluctuates widely

What was the main focus of the additional example with Jill's data?

• Temperature over a week

• Population growth over a year

• Sales over a month

• Rainfall over six days

Why is it important to label the axes on a graph?

• To comply with graph standards

• To make the graph colorful

• To provide clarity on what the graph represents

• To confuse the viewers
