The Data Displayer is an efficient way to calculate and graph data so you can jump right to analyzing the results.

#### The Data Displayer allows you to analyze data from different perspectives by providing four data analysis tools:

• a mean, median, & mode calculator
• a box-and-whisker plot graphing generator
• a scatterplot graphing generator
• a standard deviation calculator

### Ideas for Use:

• EXERCISE YOUR ANALYSIS SKILLS: Check out data through the different calculator & graphing tools to paint a more complete picture of what each tool can help you analyze.
• STUDY THE EFFECTS OF ADJUSTMENTS: Click into any preloaded data table to edit the data. How do making adjustments to the data change the resulting calculation or graph?
• TO THE MAX: Get the most out of each data set using the data analysis question that pops up at the bottom. Give yourself a chance to draw your own conclusions before you peek at the answer!
• MAKE YOUR MARK: Enter and analyze your own custom data to form your own analysis results.

### Definitions:

• Box-and-Whisker Plot: A graph that shows the minimum, maximum, median, and quartiles for a set of data.
• Mean: The sum of a group of numbers divided by the number of numbers in the group (sometimes referred to as the average).
• Median: The middle number in a group of numbers arranged in ascending order. When two numbers are in the middle, the median is the mean of these two numbers.
• Mode: The number(s) that appears most often in a group of numbers (note: not all data sets have a mode).
• Scatterplot: A graph using ordered pairs to determine the relationship between variables in two data sets.
• Standard Deviation: A measure of how spread out a set of numbers is from its mean. The higher the standard deviation, the more spread out the set is.

### Choosing Your Data to Analyze:

Once you choose one of the above tools on the opening screen, you’ll see a dropdown menu that allows you to choose the type of data set you’d like to analyze.

#### Each of the following data options can be used with any of the four tools.

1. Custom (Your Own Data): Analyze your own data by entering your own variables (max 100 rows).
2. Sports (Preloaded Data): Analyze data to help you understand the performance of baseball teams and players.
3. Agriculture (Preloaded Data): Analyze data to give you insights into the business of agriculture.
4. Movies (Preloaded Data): Analyze data that takes you behind the scenes of the film business.
