Dot Plot, Histogram & Box Plot

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of data points plotted on a simple scale, typically using dots to represent individual data points.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, where the data is divided into intervals (bins) and the frequency of data points in each interval is represented by the height of bars.

Front

What is a box plot?

Back

A box plot, or box-and-whisker plot, is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile, median, third quartile, and maximum.

Front

What does the median represent in a box plot?

Back

The median represents the middle value of a data set when it is ordered from least to greatest, dividing the data into two equal halves.

Front

How do you find the mean of a set of numbers?

Back

To find the mean, add all the numbers together and then divide by the total count of the numbers.

Front

What is an interval in statistics?

Back

An interval is a range of numbers that represents a specific segment of data.

Front

What does the height of a bar in a histogram represent?

Back

The height of a bar in a histogram represents the frequency of data points that fall within the corresponding interval.

Front

How can you identify the mode from a dot plot?

Back

The mode is identified as the value that appears most frequently in the dot plot.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the central tendency, variability, and distribution of a data set.

Front

How do you interpret the whiskers in a box plot?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, indicating the range of the data.
