What is a box plot?

Back

A box plot is a graphical representation of data that shows the distribution of a dataset based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

What does a histogram represent?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data by showing the number of data points that fall within specified ranges (bins).

Front

What is a dot plot?

Back

A dot plot is a simple statistical chart that consists of dots plotted above a number line, where each dot represents one data point.

Front

How do you interpret the median in a box plot?

Back

The median in a box plot is represented by a line inside the box and indicates the middle value of the dataset when it is ordered.

Front

What do the whiskers in a box plot represent?

Back

The whiskers in a box plot extend from the box to the smallest and largest values that are not outliers, showing the range of the data.

Front

What is the purpose of using a histogram?

Back

The purpose of using a histogram is to visualize the distribution of data, allowing for easy identification of patterns, trends, and outliers.

Front

How can you identify outliers in a box plot?

Back

Outliers in a box plot are typically represented as individual points that fall outside the whiskers, indicating values that are significantly higher or lower than the rest of the data.

Front

What is the difference between a statistical question and a non-statistical question?

Back

A statistical question anticipates variability in the data and can be answered by collecting data, while a non-statistical question has a fixed answer and does not involve data collection.

Front

How do you find the range of a dataset?

Back

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

Front

What does it mean if a histogram is skewed to the right?

Back

If a histogram is skewed to the right, it means that the majority of the data points are concentrated on the left side, with a tail extending to the right.
