Dot plots and Box plots

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots representing the frequency of data points along a number line.

Front

What is a box plot?

Back

A box plot, or box-and-whisker plot, is a graphical representation of data that shows the median, quartiles, and extremes of a dataset.

Front

What does the median represent in a dataset?

Back

The median is the middle value when the data points are arranged in ascending order.

Front

How do you find the mode of a dataset?

Back

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

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in a dataset.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in a dataset.

Front

What are quartiles in statistics?

Back

Quartiles are values that divide a dataset into four equal parts, with Q1 being the first quartile, Q2 the median, and Q3 the third quartile.

Front

How do you calculate the upper quartile (Q3)?

Back

Q3 is the median of the upper half of the dataset, excluding the median if the number of data points is odd.

Front

What is the interquartile range (IQR)?

Back

The IQR is the difference between the upper quartile (Q3) and the lower quartile (Q1), representing the middle 50% of the data.

Front

What does a dot plot help visualize?

Back

A dot plot helps visualize the distribution and frequency of data points in a dataset.
