There are all kinds of charts and graphs, some are easy to understand while others can be pretty tricky. There are many different types because each one has a fairly specific use. Bar graphs can be used to show how something changes over time or to compare items. They have an x-axis (horizontal) and a y-axis (vertical). Typically, the x-axis has numbers for the time period or what is being measured, and the y-axis has numbers for the amount of stuff being measured. Bar graphs are good when you're plotting data that spans many years (or days, weeks..), has really big changes from year to year (or day to day..), or when you are comparing things.

An example using real education data would be if you wanted to show the most popular bachelor's degrees (business, education, etc.) that students received in college in a given year.

A bar graph (also known as a bar chart or bar diagram) is a visual tool that uses bars to compare data among categories. A bar graph may run horizontally or vertically. The important thing to know is that the longer the bar, the greater its value. Bar graphs consist of two axes.

Bar Graph: A bar graph is a chart that plots data with rectangular bars representing the total amount of data for that category. A bar chart is a style of bar graph; it is often used to represent. Hey Everyone,We hope you and your child enjoyed the scavenger hunt! If you are looking for more opportunities for your child to do in addition to these videos and activities, feel free to encourage more independent reading and writing.

You are now ready to create your own bar graph..

Here the Factory is our independent variable, since there is no unit of measurement for factories and no 'order' to the factories, the independent variable is nominal. The dependent variable is scalar, measured in defects/1,000 cars. Since the scalar dependent variable has a natural zero point (i.e., absolute or ratio), all of the bars are anchored to the horizontal axis, giving a common point of measurement.

Bar graphs can be shown with the dependent variable on the horizontal scale. This type of bar graph is typically referred to as a horizontal bar graph. Otherwise the layout is similar to the vertical bar graph. Note in the example above, that when you have well-defined zero point (ratio and absolute values) and both positive and negative values, you can place your vertical (independent variable) axis at the zero value of the dependent variable scale. The negative and positive bars are clearly differentiated from each other both in terms of the direction they point and their color.

Range bar graphs represents the dependent variable as interval data. The bars rather than starting at a common zero point, begin at first dependent variable value for that particular bar. Just as with simple bar graphs, range bar graphs can be either horizontal or vertical. Notice in the horizontal example above, a reference line is used to indicate a common key dependent variable value.

Histograms are similar to simple bar graphs except that each bar represents a range of independent variable values rather than just a single value. What makes this different from a regular bar graph is that each bar represents a summary of data rather than an independent value. For this type of graph, the dependent variable is almost always a scalar scale representing the count, or number, of how many of a sample fall within each range of the independent variable. In the example above, the sample is all the females in the U.S. The independent variable is age, which as been grouped into ranges of 5 years each. You should try and keep the ranges for each bar uniform (5 years in this case), with the exception possibly being the first and/or last range.
