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 ranges (bins).

Front

How do you determine the height of a bar in a histogram?

Back

The height of a bar in a histogram represents the number of data points that fall within the range of that bar (bin).

Front

What is the purpose of using a stem-and-leaf plot?

Back

A stem-and-leaf plot is used to display quantitative data in a way that retains the original data values while showing the distribution.

Front

What does the x-axis represent in a histogram?

Back

The x-axis represents the intervals (bins) of the data, showing the ranges of values.

Front

What does the y-axis represent in a histogram?

Back

The y-axis represents the frequency of data points that fall within each interval (bin).

Front

How can you find the mode from a histogram?

Back

The mode is the interval with the highest bar (frequency) in the histogram.

Front

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

Back

A histogram displays continuous data and shows frequency distribution, while a bar graph displays categorical data and compares different groups.

Front

What information can you not obtain from a histogram?

Back

You cannot determine exact values or individual data points from a histogram; it only shows frequency within ranges.

Front

How do you interpret the shape of a histogram?

Back

The shape of a histogram can indicate the distribution of data, such as normal, skewed, or uniform distributions.

Front

What is a bin in the context of a histogram?

Back

A bin is a range of values that groups data points together in a histogram.
