What is a Box Plot?

Back

A Box Plot is a graphical representation of data that displays the distribution of a dataset based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. It does not show original data clearly and does not allow for easy identification of mean and mode.

What is a Dot Plot?

Back

A Dot Plot is a simple graphic display that uses dots to represent the frequency of data points in categories or groups. It allows for easy comparison of frequencies.

Front

What is a Histogram?

Back

A Histogram is a graphical representation that organizes a group of data points into user-specified ranges (bins). It shows the frequency of data within each bin.

Front

What is a Line Graph?

Back

A Line Graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is often used to visualize data trends over time.

Front

What is a Scatter Plot?

Back

A Scatter Plot is a graph that uses dots to represent the values obtained for two different variables - one plotted along the x-axis and the other plotted along the y-axis. It helps to identify relationships between the variables.

Front

True or False: Changing the scales in a graph can make the data look very different.

Back

True. Changing the scales can distort the representation of the data.

Front

True or False: When comparing two or more sets of data, the scales must be consistent.

Back

True. Consistent scales are necessary for accurate comparison of data sets.

Front

What is the purpose of using 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 dataset.

Front

What does a Dot Plot help to visualize?

Back

A Dot Plot helps to visualize the frequency of data points in different categories, making it easy to compare groups.

What is the main advantage of using a Histogram?

Back

The main advantage of using a Histogram is that it provides a visual representation of the distribution of numerical data, allowing for easy identification of patterns.
