Circle Graphs
What percent of a circle is represented by a 90 degree angle?
What is 25%?
True or False: Bars in a bar graph ALWAYS touch.
What is false?
How are histograms different from bar graphs?
Histogram bars touch.
What do broken line graphs usually show?
What is changes over time?
When is legend not needed?
Single bar graphs.
What does a circle graph represent?
What is a whole OR 100% of something?
What is the difference between a vertical bar graph and a horizontal bar graph?
The bars run side-to-side in a horizontal bar graph, and up-and-down in a vertical bar graph.
Why are the bars (intervals) in a histogram always equal in width?
To make the comparisons fair and consistent; to avoid misinterpretation of data.
What do the points on a broken line graph represent?
What is a specific value at a given time or condition?
What does the term interpolate mean?
To estimate a value between two values shown on the graph.
What four items do circle graphs need in order to be complete?
What is a title, labels, sectors, and legend?
What does a double bar graph allow you to do that a single bar graph does not?
Compare two groups or sets of data side by side for the same categories.
What kind of data works best for histograms?
Numerical data that ranges, such as ages, test scores, measurements, etc.
Why are the points connected with dashed/dotted lines?
To show the pattern or trend between values.
Which type of graph would be most useful to show how sales increased and decreased each day over a week?
What is a broken line graph?
When labelling sectors on a circle graph, what do we label them with?
What is percent?
What makes a stacked bar graph different from a double bar graph?
In a stacked bar graph, data for each category is placed on top of each other in a single bar to show the total and parts together, while a double bar graph shows two separate bars for each category.
Histograms display which type of data?
Continuous data.
What is one advantage or a broken line graph over a bar graph?
BONUS: What is Sydney's son's name?
Torrin
A circle graph shows: Dogs 40%, Cats 35%, Other 25%. If 240 people were surveyed, how many chose cats?
What is 84 people?
Bar graphs display which type of data?
What is discrete data?
What does the height of each bar in a histogram represent?
When would you choose to use a histogram instead of a bar graph?
When the data is numerical and continuous, and you want to group it ranges instead of comparing separate categories.
What does the term extrapolate mean?
To predict a value from beyond the given data shown on the graph.
