Understanding Misleading Graphs and Statistics

What are the two main types of misleading graphs and statistics discussed in the lesson?

• Graphs with different intervals and statistics using non-representative measures of center

• Graphs with identical scales and statistics using the median

• Graphs with consistent intervals and statistics using the mode

• Graphs with uniform data and statistics using the range

In the Stanley Cup graph example, why is Messier's performance misleadingly represented?

• The graph uses a logarithmic scale

• Messier's points are shown as less than Curry's

• The graph omits Curry's data entirely

• Messier's image is twice the size of Curry's, exaggerating the difference

How does the Spring Dance ticket price graph demonstrate misleading graph techniques?

• By omitting data from certain years

• By using different intervals to make price increases appear more or less significant

• By using a pie chart instead of a bar graph

• By changing the color of the bars

Which graph would a student council use to show that ticket price increases are not significant?

• Graph with a logarithmic scale

• Graph with no intervals

• Graph with larger intervals

• Graph with smaller intervals

What is the main issue with the line graph showing business profitability?

• It uses a consistent interval throughout

• It changes intervals midway, exaggerating profits

• It uses a logarithmic scale

• It omits data from certain months

Why is the amusement park's claim about roller coaster heights misleading?

• The park uses a pie chart to display heights

• All coasters are exactly the same height

• The median height is used instead of the mean

• The mean height is skewed by one very tall coaster

Which measure of center would be more appropriate for the roller coaster heights?

• Range

• Mode

• Mean

• Median

What is the effect of using a very low-priced sofa in calculating the mean price?

• It decreases the mean price

• It makes the mean equal to the median

• It increases the mean price

• It has no effect on the mean price

Which measure of center is most affected by outliers?

• Mode

• Range

• Median

• Mean

Why might a sofa store advertise the mean price instead of the median?

• The mean is higher than the median

• The mean is lower than the median

• The mean is the same as the median

• The mean is not affected by outliers
