Exploring Frequency Tables and Histograms

What does a frequency table display?

• The sum of all data values

• The specific data values in a dataset

• The number of times a value occurs in each category or interval

• The average of the data values

What is a histogram?

• A line graph showing data trends over time

• A pie chart representing data proportions

• A bar graph showing the number of values in each category or interval

• A scatter plot showing data distribution

What is a key characteristic of the bars in a histogram?

• They are always the same height

• They are always touching

• They are always separated by gaps

• They are always different colors

In a frequency table, what does the interval 6-10 represent?

• The highest value in the dataset

• The average of values between 6 and 10

• The number of data values between 6 and 10

• The sum of all values between 6 and 10

What should you check to ensure the accuracy of your frequency table?

• The table has a title

• The data values are in ascending order

• The intervals are all the same length

• The total number of data values matches the sum of frequencies

What does the highest frequency in a frequency table indicate?

• The most common range of values

• The average value of the dataset

• The highest value in the dataset

• The total number of data values

In the context of a histogram, what does a gap between bars indicate?

• A missing data value

• A change in data collection method

• A range with no data values

• An error in the data

How many games did Kendra play last season if the histogram shows 3 games in the 0-4 range, 6 in the 10-14 range, 2 in the 15-19 range, and 1 in the 20-24 range?

• 13

• 12

• 11

• 10

When is a dot plot most suitable?

• When you need to find the median easily

• For small datasets showing individual data values

• For large datasets

• When you need to represent data in intervals

Which data representation method is best for finding the median easily?

• Line graph

• Dot plot

• Histogram

• Box plot
