StandardState Performance Indicator Basic Algebra Skills*Solve Multistep single variable equation Analyze Statistical Data* SPI Compute, compare and explain summary statistics for distributions of data including measures of center and spread. SPI Compare data sets using graphs and summary statistics. Use Linear Regression to analyze Scatter Plots* SPI Analyze patterns in a scatter-plot and describe relationships in both linear and non-linear data. SPI Find the regression curve that best fits both linear and non-linear data (using technology such as a graphing calculator) and use it to make predictions. SPI Determine/recognize when the correlation coefficient measures goodness of fit. Identify Interquartile RangeSPI Apply the characteristics of the normal distribution. Recognize Random vs Observed Experiments SPI Determine differences between randomized experiments and observational studies. Recognize Data Bias SPI Recognize and describe errors in data collection and analysis as well as identifying representations of data as being accurate or misleading. Identify Domain, Range and Restrictions (Linear Function)* SPI Describe the domain and range of functions and articulate restrictions imposed either by the operations or by the contextual situations which the functions represent. Evaluate Arithmetic Sequences* SPI Use the formulas for the general term and summation of finite arithmetic and both finite and infinite geometric series.

 Divide Room down Middle, move into groups of three  Working together define the following:  Survey  Population  Sample

1. Biased vs Unbiased 2. Survey Design 3. Experiment vs Observational Study 4. Correlation vs Causation Review the examples on your sheet and on pages 745 – 747 in your book. Answer Questions on worksheet When directed return to groups of three, sharing your information to make sure the entire group understands all three concepts. Complete Round 2, work together on practice p

A.Yes; they will most likely think football is the most popular sport. B.Yes; no obvious bias exists. C.No; they will most likely think football is the most popular sport. D.No; no obvious bias exists. A. State whether the following method would produce a random sample. Explain. surveying people going into a football game to find out the most popular sport

A.Yes; no obvious bias exists in asking every 5th person. B.Yes; they will most likely be biased toward drama films. C.No; no obvious bias exists in asking every 5th person. D.No; they will most likely be biased towards drama films. B. State whether the following method would produce a random sample. Explain. surveying every fifth person going into a mall to find out the most popular kind of movie

A.Yes; they are more likely to say yes if that are on their home computer a lot. B.Yes; no obvious bias exists in asking people online if they own fish. C.No; they are more likely to say yes if they are on their home computer a lot. D.No; there is an obvious bias that exists in asking people online if they own fish. C. State whether the following method would produce a random sample. Explain. conducting an online survey to determine what percent of people own fish as pets

Survey Design SPORTS Which question will determine the most popular spectator sport? A. Isn’t football an exciting sport to watch? Answer: This question is biased in favor of tennis. B. What is your favorite sport to watch? Answer:This question is biased in favor of football. Answer: This is an unbiased question that will produce the answer being sought. C. Do you like to watch tennis matches?

A.Do you prefer milk chocolate or dark chocolate? B.Do you like to put ice cream on top of a piece of apple pie? C.What is your favorite dessert to eat? D.None of these DESSERT Will this question determine the most popular dessert? Which question is best to determine the most popular dessert?

A.experiment; treatment group: students who play sports; control group: students who do not play sports; biased B.experiment; treatment group: students who do not play sports; control group: students who play sports C.experiment; treatment group: students who do not play sports; control group: students who play sports; not biased D.observational study; treatment group: students who play sports; control group: students who do not play sports A. EXPERIMENT State whether the example represents an experiment or an observational study. If it is an experiment, identify the control group and the treatment group. Then determine whether there is a bias. Find 100 students, half of whom play sports after school. Compare their number of siblings.

EXPERIMENT State whether the example represents an experiment or an observational study. If it is an experiment, identify the control group and the treatment group. Then determine whether there is a bias. Find 100 students and randomly split them into two groups. One group eats breakfast and the other group does not.

A.survey B.observational study C.experiment A. Determine whether the situation calls for a survey, an observational study, or an experiment. You want to find out if playing years of soccer affects lung capacity.
