Lesson 26: Measures of Central Tendency
// EQ: What are the measures of central tendency, and how do we find them? // Notes: [|Lesson261011.pdf] Worksheet: [|Lesson26Wkst1011.pdf] Measures of Central Tendency Application of Central Tendency (Video)

Using the TI-83/84
1. STAT → 1:Edit... 2. Enter data in a list 3. STAT → 2:SortA( 4. Enter your list: 2ND → 1 for L1, 2ND → 2 for L2, etc.  5. STAT → 1:Edit... to view sorted data
 * Enter data **

1. Make sure data is in your list 2. 2ND → STAT → MATH → 3:mean( or 4:median( and enter your list
 * Find mean and median: **

Lesson 27: Stem-and-Leaf and Box-and-Whisker Plots
// EQ: // // How do you create and utilize stem-and-leaf and box-and-whisker plots? // Notes: [|Lesson271011.pdf] Worksheet: [|Lesson27Wkst1011.pdf] Stem-and-Leaf Plots Box-and-Whisker Plots

On the TI-83/84
1. Enter the data in a list 2. 2nd → Stat Plot 3. Choose a plot and adjust 4. Zoom → ZoomStat 5. Examine the graph 6. Trace

Lesson 28: Scatterplots and Lines of Best Fit
// EQ: How do you use a scatterplot to predict possible outcomes of a situation? // Notes: [|Lesson281011.pdf] Worksheet: [|Lesson28Wkst1011.pdf] Scatterplots and lines of best fit

**Scatterplots in the TI83/84**
1. Enter the data: Stat → 1:Edit... 2. L1 = Independent, L2 = Dependent 3. 2nd, Y= → 1:Plot1... 4. Turn on → Choose scatterplot → Xlist is independent, Ylist is dependent → Choose a mark 5. Zoom → 9:ZoomStat 6. Stat → Calc → 4:LinReg(ax+b) 7. LinReg(ax+b) L1,L2,Y1
 * To get Y1: Alpha → F4 (Trace) → Y1 (TI-84 New OS)
 * To get Y1: Vars → Y-Vars → 1:Function → Y1 (TI-83/TI-84 Old OS)

8. Graph
 * Make sure the Diagnostic is on to see the coefficient of correlation: 2nd, 0 → DiagnosticOn

Lesson 29: Probability
// EQ: How do you calculate and apply the principles of probability? // Notes: [|Lesson291011.pdf] Worksheet: [|Lesson29Wkst1011.pdf] Probability More on Probability Tree Diagrams

Lesson 30: Permutations, Combinations, and Probability
// EQ: How do you determine permutations and combinations and use them to find probabilities? // Notes: [|Lesson301011.pdf] Worksheet: [|Lesson30Wkst1011.pdf] Combinations and Permutations: What's the Difference? Permutations Combinations

Lesson 31: Odds and Probability
// EQ: How do you calculate odds in favor or against and compare it to probability? // Notes: [|Lesson311011.pdf] Worksheet: [|Lesson31Wkst1011.pdf] Probability and Odds

Lesson 32: Predicting from Data
// EQ: How do you data from an experiment to predict further outcomes? // Notes: [|Lesson321011.pdf] Worksheet: [|Lesson32Wkst1011.pdf]
