Histograms FLASHCARD

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within specified intervals (bins).

Front

What are intervals in a histogram?

Back

Intervals (or bins) are the ranges of values that group data points in a histogram. Each interval represents a specific range of values.

Front

How do you determine the frequency in a histogram?

Back

Frequency is determined by counting the number of data points that fall within each interval.

Front

What is the importance of labeling axes in a histogram?

Back

Labeling axes is crucial as it provides context to the data, indicating what the intervals represent and the frequency scale.

Front

What does it mean if intervals in a histogram overlap?

Back

Overlapping intervals can lead to confusion and misinterpretation of data, as it may not be clear which interval a data point belongs to.

Front

How can you identify the interval with the greatest frequency in a histogram?

Back

The interval with the greatest frequency is the one that has the tallest bar in the histogram.

Front

What type of data is best represented by a histogram?

Back

Histograms are best for continuous data, where values can fall within a range.

Front

What is the difference between a histogram and a bar graph?

Back

A histogram displays continuous data in intervals, while a bar graph represents categorical data with distinct bars.

Front

What is a common mistake when creating a histogram?

Back

A common mistake is using intervals that are too small, which can make the histogram difficult to read.

Front

How do you calculate the total frequency in a histogram?

Back

Total frequency is calculated by summing the frequencies of all intervals.
