Properties of Histograms

What type of data do histograms use?

• Ordinal data

• Alphabetical data

• Categorical data

• Quantitative data

What distinguishes a histogram's bars from a bar graph's?

• Histograms' bars do not have gaps between them

• Bar graphs use quantitative data

• Histograms have gaps between bars

• Histograms' bars have varying widths

What does the y-axis in a histogram typically represent?

• Data range

• Bin size

• Frequency or counts

• Percentage

How is the bin size for a histogram determined?

• Based on the range of data

• Using the highest value in the data set

• Always set to 10

• By the number of data points

What is the first step in creating a histogram?

• Labeling the axes

• Drawing the bars

• Calculating the mean of the data

• Determining the bin size

How are data points allocated to bins in a histogram?

• Equally across all bins

• Based on their value

• Randomly

• According to their frequency

What does a bracket symbol in a histogram's frequency table indicate?

• The end of the histogram

• The value is included in the bin

• The value is excluded from the bin

• The start of a new bin

Where do you start plotting the x-axis in a histogram?

• At a multiple of the bin size

• Anywhere, as long as it's evenly spaced

• At zero

• At the lowest data point

What should the height of a bar in a histogram represent?

• The frequency of data points in the bin

• The range of data

• The bin size

• The average value of the data

Why is it important to label the axes in a histogram?

• To provide clarity on what the histogram represents

• To comply with mathematical standards

• To make the histogram look complete

• To indicate the type of data
