**Data Management**

During this math unit, students will:

• Collect and organize categorical, discrete, or continuous primary data and secondary data and display the data using charts and graphs, including circle frequency tables with intervals, circle graphs, histograms, and scatter plots;

• Apply a variety of data management tools and strategies to make convincing arguments about data.

### Below are some helpful videos that will reinforce what we learn in class.

**Creating a Scatter Plot**

**How to Create a Circle Graph**

**Scatter Plot: Positive and Negative Correlations**

**Creating Frequency Tables**

**Creating a Histogram**

**Skewness**

**Central Tendency **

Mean, Median, Mode. The term **central tendency** refers to the “middle” value or perhaps a typical value of the data, and is measured using the mean, median, or mode. Each of these measures is calculated differently, and the one that is best to use depends upon the situation.
