Dot Plot, Histogram, Box Plot

Front

What is a dot plot?

Back

A dot plot is a statistical chart that uses dots to represent the frequency of data points in a dataset. Each dot represents one occurrence of a value.

Front

How do you interpret a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, where the data is divided into bins or intervals. The height of each bar represents the frequency of data points within that interval.

Front

What is a box plot?

Back

A box plot, or whisker plot, is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

What does the upper quartile (Q3) represent?

Back

The upper quartile (Q3) is the median of the upper half of a dataset, representing the value below which 75% of the data falls.

Front

How do you calculate the mean of a dataset?

Back

To calculate the mean, sum all the values in the dataset and then divide by the number of values.

Front

What is the median?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle values.

Front

What is the mode?

Back

The mode is the value that appears most frequently in a dataset. A dataset may have one mode, more than one mode, or no mode at all.

Front

How do you find the range of a dataset?

Back

The range is found by subtracting the smallest value in the dataset from the largest value.

Front

What is a frequency distribution?

Back

A frequency distribution is a summary of how often each value occurs in a dataset, often represented in a table or graph.

Front

What is the purpose of a box plot?

Back

A box plot visually summarizes the distribution of a dataset, highlighting the median, quartiles, and potential outliers.
