Line Plots, Histograms, & Box Plots

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line, using X's or dots to represent each data point.

Front

What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data, where the bars touch each other to indicate continuous data.

Front

What is a box plot (box and whisker plot)?

Back

A box plot is a graphical representation that displays the distribution of a dataset based on five summary statistics: minimum, first quartile, median, third quartile, and maximum.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the data in ascending order and identify the middle value. If there is an even number of values, average the two middle values.

Front

What does the median represent in a dataset?

Back

The median represents the middle value of a dataset, dividing it into two equal halves.

Front

What is the mode of a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

How do you interpret a box plot?

Back

A box plot shows the spread and center of a dataset. The box represents the interquartile range (IQR), the line inside the box is the median, and the 'whiskers' show the range of the data.

Front

What is the range of a dataset?

Back

The range is the difference between the maximum and minimum values in a dataset.

Front

How do you create a histogram?

Back

To create a histogram, divide the data into intervals (bins), count the number of data points in each interval, and draw bars for each interval with heights corresponding to the counts.

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the median of the lower half of a dataset, representing the 25th percentile.
