What does the tallest bar on a bar graph tell you?

What does the tallest bar on a bar graph tell you?

Solution: The vertical axis in the bar graph is labeled “Historically active volcanoes,” so the tallest bar represents the country with the most historically active volcanoes. Because the United States has the tallest bar, it has the most historically active volcanoes.

What does each bar represent in a bar graph?

A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value. Some bar graphs present bars clustered in groups of more than one, showing the values of more than one measured variable.

What does a bar graph best show?

a Bar Graph. Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

How do you make a bar graph show from lowest to highest?

Head to the Data tab. Click the Sort icon. You can sort either column. To arrange your bar chart from greatest to least, you sort the # of votes column from largest to smallest.

How is a bar graph labeled?

Bar graphs have a labeled x-axis (horizontal axis) and y-axis (vertical axis). When experimental data is graphed, the independent variable is graphed on the x-axis, while the dependent variable is graphed on the y-axis.

How many variables does a bar graph have?

A multiple bar graph depicting data using two independent variables is created in the same way as a simple bar graph: Some things to note when creating this multiple bar graph: The first independent variable, Mammal, is still in the first column, with the dependent variable values (Count) in columns two and three.

What does each bar represent?

Bars of uniform width can be drawn horizontally or vertically with equal spacing between them and then the length of each bar represents the given number. Such method of representing data is called a bar diagram or a bar graph. Bar graphs or bar diagrams are helpful in representing the data visually.

How many axes does a bar graph have?

two axes
Bar graphs consist of two axes. On a vertical bar graph, as shown above, the horizontal axis (or x-axis) shows the data categories. In this example, they are years. The vertical axis (or y-axis) is the scale.

What bar plots show?

Bar graphs are ideal for comparing two or more values, or values over time. Data is displayed either horizontally or vertically. Single bar graphs are used to convey discrete values of an item within a category. For instance, a bar graph could display the number of males with a certain trait for specific ages.

What is the best data for a bar graph?

Bar Graphs are good when your data is in categories (such as “Comedy”, “Drama”, etc). But when you have continuous data (such as a person’s height) then use a Histogram. It is best to leave gaps between the bars of a Bar Graph, so it doesn’t look like a Histogram.

How do you sort a chart from highest to lowest in Excel?

Sort numbers

  1. Select a cell in the column you want to sort.
  2. On the Data tab, in the Sort & Filter group, do one of the following: To sort from low to high, click (Sort Smallest to Largest). To sort from high to low, click (Sort Largest to Smallest).

What makes a bar graph a bar chart?

Bar graphs have three key attributes: A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time.

Which is the closest relative to a bar chart?

For bar charts that depict summary statistics, the line chart is the closest relative. Like the relationship from the bar chart to a histogram, a line chart’s primary variable is typically continuous and numeric, emphasized by the continuous line between points.

What do the values in the first column of a bar chart mean?

Values down the first column indicate levels of the primary categorical variable. Each column after the first will then correspond with one level of the secondary categorical variable. The main cell values indicate the length of each sub-bar in the plot.

What does a stacked bar chart look like?

What is a stacked bar chart? The stacked bar chart (aka stacked bar graph) extends the standard bar chart from looking at numeric values across one categorical variable to two. Each bar in a standard bar chart is divided into a number of sub-bars stacked end to end, each one corresponding to a level of the second categorical variable.
