Exploring Histograms for Statistical Analysis

This lesson covers the use of histograms to answer statistical questions. It includes comparing text message data from sixth and seventh graders, creating a histogram for running times with less variability, solving inequalities related to the number of dimes, and ordering numbers from greatest to least. The lesson concludes with a summary of the key points discussed.

Do sixth and seventh graders have the same center value for their text message data?

• Cannot be determined from the data

• No, seventh graders have a higher center

• No, sixth graders have a higher center

• Yes, both have a center of 100

Which grade's text message data shows a greater spread?

• Cannot be determined

• Both are the same

• Seventh grade

• Sixth grade

How can a histogram's variability be reduced while keeping the center constant?

• By adding more data points

• By removing data points

• By narrowing the range of data

• By increasing the range of data

What is the center of the distribution for the running times of 46 sixth graders?

• Approximately 10 minutes

• Approximately 12 minutes

• Approximately 14 minutes

• Approximately 8 minutes

Which inequalities correctly represent the number of dimes Jada has?

• d > 5 and d < 9

• d >= 4 and d <= 9

• d >= 3 and d <= 10

• d > 3 and d < 10

Can Jada have 10 dimes?

• Yes, if she has more than a dollar

• No, because it exceeds the value limit

• Yes, exactly 10

• No, because it's less than the value limit

How many solutions satisfy the inequalities for the number of dimes Jada has?

• Seven solutions

• Six solutions

• Eight solutions

• Five solutions

Which number is the greatest in the list?

• -3.5

• -5.4

• 4.1

• 4.7

Which number is the least in the list?

• 4.0

• -5.4

• -3.5

• -4.0

In ordering the numbers from greatest to least, which comes first?

• 4.7

• 4.1

• -4.0

• -3.5
