- What is a bar graph?
- A chart that uses rectangular bars to show and compare amounts or frequencies of categories.
- What does the vertical axis on a bar graph show?
- The quantities or amounts being measured, represented by the height of each bar.
- What does the horizontal axis on a bar graph show?
- The categories or labels being compared.
- How do you find a specific value on a bar graph?
- Locate the category on the horizontal axis, find the top of its bar, then read across to the vertical axis scale.
- When is a bar graph the best choice to display data?
- When you want to compare quantities or amounts across different categories.
- What is a line graph?
- A chart that uses points connected by line segments to show how data changes over time or continuous variables.
- What does a line connecting points on a line graph represent?
- The pattern or trend showing how values change from one point to the next.
- How do you read the coordinates of a point on a line graph?
- Find the horizontal value on the x-axis and the vertical value on the y-axis where the point is located.
- What type of data change does a line graph show best?
- Change over time or continuous change in a variable.
- What is a pie chart?
- A circular chart divided into slices where each slice represents a portion or percentage of the whole.
- What does each slice in a pie chart represent?
- A category or part of the data, usually shown as a count or percentage of the total.
- What must all the slices in a pie chart add up to?
- 100 percent of the whole, or the complete total of all the data.
- How do you compare the sizes of slices in a pie chart?
- Compare the angle or area of each slice; larger slices represent larger portions of the whole.
- What is the scale on a bar graph?
- The sequence of numbers on an axis that shows the range and units of values being measured.
- How do you compare two bars on a bar graph?
- Look at the height of each bar; the taller bar represents the larger amount.
