5thHFlashcard 3, Chapter 2...Stem and Leaf, Dot Plots & Circle graphs

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values while showing their distribution.

Front

How do you interpret a dot plot?

Back

A dot plot is a simple way to display data points along a number line, where each dot represents one occurrence of a value. It helps visualize the frequency of data.

Front

What is a circle graph (pie chart)?

Back

A circle graph, or pie chart, is a circular statistical graphic divided into slices to illustrate numerical proportions. Each slice represents a category's contribution to the total.

Front

What does the total percentage of a circle graph represent?

Back

The total percentage of a circle graph represents 100%, indicating the whole dataset.

Front

How do you convert a decimal to a percentage?

Back

To convert a decimal to a percentage, multiply the decimal by 100 and add a percent sign. For example, 0.604 becomes 60.4%.

Front

What is the purpose of using a dot plot?

Back

Dot plots are used to display small to moderate-sized data sets and to show the distribution and frequency of data points.

Front

How do you find the mode in a stem-and-leaf plot?

Back

The mode is the value that appears most frequently in the data set, which can be identified by looking for the stem with the most leaves.

Front

What is the difference between a bar graph and a circle graph?

Back

A bar graph displays data with rectangular bars representing different categories, while a circle graph shows proportions of a whole in a circular format.

Front

How do you calculate the percentage of a specific category in a circle graph?

Back

To calculate the percentage of a specific category, divide the part (value of the category) by the whole (total value) and multiply by 100.

Front

What does a frequency distribution show?

Back

A frequency distribution shows how often each value occurs in a dataset, often represented in tables or graphs.
