Open Ended

Explain the difference between discrete and continuous quantitative variables.

Multiple Choice

What are the two main types of quantitative variables?

• Discrete and Continuous

• Nominal and Ordinal

Multiple Select

Select all statements that are true about quantitative variables.

• They can be described with numerical data.

Open Ended

How does a frequency table for discrete data compare to a frequency table for categorical data?

Multiple Choice

Which of the following is a key difference between a histogram for discrete quantitative data and a bar graph for categorical data?

• The bars in a histogram for discrete quantitative data will touch each other.

• The bars in a histogram for discrete quantitative data will be spaced apart.

• The y-axis in a histogram for discrete quantitative data is labeled with categories.

• The x-axis in a histogram for discrete quantitative data can be in any order.

Open Ended

Explain why the bars in a histogram for discrete quantitative data must touch each other and why the x-axis must go in order from least to greatest.

Multiple Choice

What is the purpose of labeling the x-axis with values between the bars in a histogram for discrete quantitative data?

• To indicate the range of values included in each bar

• To show the frequency of each value

• To separate the bars visually

• To display the mean value

Open Ended

How does the representation of data in a frequency table compare to its representation in a histogram, based on the example of number of pets owned by students?

Multiple Select

Based on the frequency table and histogram shown, which of the following statements are true?

• The first bar represents students who own 0 pets.

• The frequency of students who own 2 pets is 2.

• The histogram shows the number of pets owned by students.

• The upper boundary of each bar is included in the count.

Open Ended

Explain why the first bar in the histogram for the number of pets owned by students goes from 0 to 1 and has a frequency of 10.

Multiple Choice

What is the relationship between the frequency table and the histogram shown for the number of pets owned by students?

• The histogram is a graphical representation of the frequency table data.

• The histogram shows different data than the frequency table.

• The frequency table is based on the histogram.

• The histogram only shows the highest frequency.

Multiple Select

Which of the following are steps needed to create a histogram from a list of data?

• Organize the data into intervals or bins

• Count the frequency for each interval

• Draw bars for each interval with heights representing frequency

• Calculate the mean of the data

Open Ended

Describe how you would use the completed frequency table to create a histogram for the football team scores.

Multiple Choice

Based on the football team scores data, which score interval had the highest frequency?

• 0 to 9

• 10 to 19

• 20 to 29

• 30 to 39

Multiple Choice

If you wanted to compare the performance of two different teams using this method, what additional information would you need?

• The names of the players

• The scores of the other team for each game

• The location of each game

• The weather conditions during each game

Multiple Choice

According to the frequency table, which score range had the highest number of games?

• 0 to 9

• 10 to 19

• 20 to 29

• 30 to 39

Multiple Choice

What is the purpose of creating a histogram from the given data?

• To show the average score

• To display the frequency of scores in intervals

• To list all individual scores

• To compare scores between different teams

Multiple Select

Which of the following can be inferred from the frequency table and histogram?

• Most games had scores between 20 and 29.

• There were very few games with scores above 40.

• Scores were evenly distributed across all ranges.

• The lowest frequency is in the 0 to 9 range.

Open Ended

Explain how the histogram visually represents the data from the frequency table. What can you infer about the distribution of scores?
