9517 types of graphs (2.1).notebook 1 September 06, 2017 Objective: Write on the goal/objective sheet and give a before classrating. Determine the types of graphs appropriate for specific data. Begin the Warm Up as I take attendance: 1. A radio talk show asked listeners to respond either yes or no to the question, Is the candidate who spends the most on a campaign the most likely to win? Fifteen people called in and nine said yes. A. What is the implied population? B. What is the variable? C. Can you detect any bias in the selection of the sample? A. B. o C. y 2.

Not allowed to go back and make up these assignments after the test. Chapter 12 Test Sept. 13th or 14th (Block day) Features of a bar graph: 1. Bars can be vertical or horizontal. 2. Bars are uniform in width and uniformly spaced. 3. The lengths of the bars represent values of the variable being displayed, the frequency of occurrence, or the percentage of occurrence. The same measurement scale is used for the length of each bar. 4. The graph is well annotated with title, labels for each bar, and vertical scale or actual value for the length of each bar. Objective: Determine the types of graphs appropriate for specific data. *watch for breaks along the vertical axis. It makes the bars appear closer in height. Bars don't touch to emphasize that it is not numerical/ continuous Checklist Bars separated each bar labeled frequency at top of each bar title x axis labeled y axis labeled scale on y axis consistent letter grade frequency
