The frequencies of each interval.

What happens if the class width is not rounded up?

The intervals may not cover the entire range.

The intervals may be too small.

The intervals may be too large.

What is the purpose of drawing bars with no gaps in a histogram?

The difference between the maximum and minimum values.

The total number of data points.

What is the main difference between a histogram and a bar chart?

Histograms display continuous data, while bar charts display categorical data.

Histograms have gaps between bars, while bar charts do not.

Histograms use vertical bars, while bar charts use horizontal bars.

Histograms show frequencies, while bar charts show proportions.

A student collected the following test scores from a class of 20 students and wants to create a histogram. The scores range from 50 to 100. Which of the following best describes the first step in creating a histogram from this data?

Organize the data into equal-width intervals (bins) and count the frequency of each interval

Connect data points with a line to show trends

Arrange the data in alphabetical order

Plot each individual score as a separate bar

A histogram shows the following distribution of ages at a community center: | Age Group | Frequency | |-----------|-----------| | 10–20 | 3 | | 20–30 | 7 | | 30–40 | 15 | | 40–50 | 14 | | 50–60 | 6 | Which of the following best describes the shape of this distribution?

Approximately symmetric (bell-shaped)

Skewed right (positively skewed)

Skewed left (negatively skewed)

A histogram has bars with the following heights (frequencies) from left to right: 2, 5, 10, 8, 3, 1. Which of the following best describes the shape of this distribution?

Skewed right (positively skewed)

Skewed left (negatively skewed)

Two histograms display the daily high temperatures (°F) for two different cities over 30 days. City A's histogram is roughly bell-shaped and centered around 75°F. City B's histogram is skewed right with most values clustered between 60°F and 70°F. Which conclusion is most accurate?

City A has a more symmetric distribution, suggesting its mean, median, and mode are approximately equal

City A and City B have the same average temperature

City B likely has a higher mean temperature than City A because it is skewed right

City B's distribution means it has more days above 80°F than City A

Which of the following is a key difference between a histogram and a bar graph?

A histogram displays continuous numerical data grouped into intervals, while a bar graph displays categorical data

A histogram is used for categorical data, while a bar graph is used for numerical data

A histogram has gaps between bars, while a bar graph does not

A histogram can only display data with fewer than 10 values

A histogram of student heights (in inches) shows the following distribution: | Height (in) | Frequency | |-------------|-----------| | 58–62 | 12 | | 62–66 | 18 | | 66–70 | 20 | | 70–74 | 6 | | 74–78 | 4 | Which of the following best describes the shape of this distribution?

Skewed right (positively skewed)

Skewed left (negatively skewed)

Two histograms compare the quiz scores of two different classes. Class 1 has a histogram skewed to the left, while Class 2 has a histogram skewed to the right. Which of the following statements is most likely true?

Class 1 likely has more high scores, while Class 2 likely has more low scores

Class 1 performed worse overall because its histogram is skewed left

Both classes performed equally well since they both have skewed distributions

Class 2 performed better because a right skew always indicates higher scores
