Module 2: Describing Data =**Vocabulary**= See Quiz Belew:

**Math Vocabulary** **1.** ** Bar Graph ** - A visual representation of horizontal & vertical bars or lines to represent data. **2.** ** Data ** - information that is gathered. **3. Graph **- A type of drawing used to represent data. **4. Percent ** - A ratio or fraction in which the second term on denominator is always 100 **5.** ** Probability **- The likelihood of an event happening. **6. Variables ** are quantities or qualities that may assume any one of a set of values. Variables may be classified as nominal, ordinal, or interval. **7. Nominal **variables use names, categories, or labels for qualitative values. Typical nominal variables include gender, ethnicity, job title, and so forth. **8. Ordinal **variables, like nominal variables, are categorical variables. However, the order or rank of the categories is meaningful. For example, staff members may be asked to indicate their satisfaction with a training course on an ordinal scale ranging from “poor” to “excellent.” Such categories could be converted to a numerical scale for further analysis. **9. Interval **variables are purely numeric variables. The nominal and ordinal variables noted above are discrete since they do not permit making statements about degree, e.g., “Person A is three times more male than person B” or “Person A rated the course as five times more excellent than person B.” Interval variables are continuous, and the difference between values is both meaningful and allows statements about extent or degree. Income and age are interval variables. **Basketball Terminology** 1. PTS: The most recognized of the basketball statistics is points...how many points a player scored for their team to help their team win. Related to how many times a player made a basket and the type of basket they made. 2. ** FG (also FGM): ** Field Goals Made - A field goal made is a basket that is made in regulation play. All baskets legally made that aren't free throws are considered field goals and worth either two or three points, depending on where they're shot from. 3. ** FG%: Field Goal Percentage ** (FG ÷ FGA) - Tells how often a player makes a shot when he/she attempts one. The percentage of shots a player has made out of that he/she has taken. Calculation: Field Goals Made ÷ Field Goal Attempts (FG ÷ FGA). //Multiply by 100 to get %// 4. 3P (also 3PM): Three Point Field Goals Made - Three point field goals made are just like two point field goals made, except for when taken from behind the 3 point line (the arc surrounding the basket). <span style="display: block; font-family: 'Times New Roman',Times,serif; font-size: 130%; text-align: left;">**5. 3P%: Three Point Field Goal Percentage ** (3P ÷ 3PA) -Three point field goal percentage tells what percentage of shot attempts a player takes from behind the three point line that are actually made (the ball goes through the hoop when they shoot it, or "throw" it toward the basket). Calculated as: Three Point Field Goals Made ÷ Three Point Field Goal Attempts (3P ÷ 3PA) multiply by 100 to get percentage. <span style="font-family: 'Times New Roman',Times,serif; font-size: 120%;">6. ** FT (also FTM): ** Free Throws Made - A free throw is a "free shot" in which the opposite team is not allowed to defend, or try to stop, the player shooting from making the basket. It is awarded when the opposite team breaks the rules, taken from 15' in front of the basket (the free throw line), and worth one point for each basket made.
