# OpenLab #7: Pick a topic (or three)

In the second half of the semester, we’ll be working on creating an annotated study guide for use in preparing for the final. Everyone will be responsible for creating a guide explaining how to do one type of problem.

Assignment (Due Thursday, April 4, 2:30pm). The list below gives an overview of topics/types of problems covered in the class.  In this assignment, you should choose THREE of the following topics that you think are interesting or might like to work on.  One or more of your choices must be from the second half of the class (items 10-18, things we have not studied yet).  Don’t be afraid to choose a topic you don’t know – you will have opportunity to learn, ask questions, and get help along the way!  Respond to this post, including your top three choices (give both the number and name of your choice, for example “my first choice is: #5, probability and counting”).

1. Frequency distributions (sec 2.1). tallying data, classes, relative frequencies and percentages, histograms
2. Measures of central tendency (sec 2.3). mean, median, mode
3. Measures of variation (sec 2.4). range, variance, standard deviation
4. Representing data visually (sec 2.2, 2.5).  stem-and-leaf plots, quartiles, box-and-whiskers plots
5. Probability and counting (sec 3.1, 3.4). combinations, permutations, sample space, events, probabilities
6. Combining probabilities (sec 3.2, 3.3). multiplication rule “and”, addition rule “or”, mutually exclusive events
7. Independent events (sec 3.2).  conditional probability, given, independent
8. Discrete probability distributions (sec 4.1).  mean, standard deviation, probability distributions based on frequency, based on tree diagram
9. Binomial distributions (sec 4.2).  trials, success, failure, binomial formula, finding probabilities in binomial distributions
10. The Normal Distribution (sec 5.1, 5.2, 5.3).  z score, finding probabilities, finding values
11. Normal Approximations to Binomial Distributions (sec 5.5). solving binomial problems using the normal distribution, continuity correction
12. Sample Mean problems (sec 5.4) finding probabilities involving the sample mean
13. Hypothesis Testing for the Mean (Large Samples) (sec 7.2), null hypothesis, alternative hypothesis, level of significance, rejection region, critical value, z-test
14. Hypothesis Testing for the Mean (Small Samples) (sec 7.3), null hypothesis, alternative hypothesis, rejection region, critical value, degrees of freedom, t-test
15. Correlation (sec 9.1), positive and negative correlation, correlation coefficient
16. Linear Regression (sec 9.2), find equation of the line of best fit/regression line, use it to predict values
17. Goodness-of-Fit Test (sec 10.1), multinomial experiments, chi-square test
18. Independence (sec 10.2), chi-square test for independence
