Unit 1: Statistics

Data Collection:

Extra Practice Problems in Big Ideas Textbook: Pg. 590 #5-10, 17, 18, 29 (I suggest practicing making a dot plot for each in addition to the directions)
Khan Academy: I recommend watching both videos in this sequence and then completing the practice problems if you are struggling.

Statistics intro: Mean, median, & modeThe mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Outliers, Shape, and Distribution

Extra Practice Problems in Big Ideas Textbook: Pg. 590 #15, 16, 31 and Pg. 604 #1, 3-4, 15 (instead of histograms, you can make dot plots to find the shape)
Khan Academy: We will only focus on symmetric (uniform distribution), left skew, and right skew. I recommend completing the "Shape of Distributions Practice" and "Describing Distributions Practice."

Classifying shapes of distributionsClassifying distributions as being symmetric, left skewed, right skewed, uniform or bimodal.

Correlation and Causation

Extra Practice Problems in Big Ideas Textbook: Pg. 199 #1-14
Khan Academy: I would definitely complete the practice problems that Khan academy has included in this article.

Scatterplots and correlation reviewA scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables.

Extra Practice Problems in Big Ideas Textbook: Pg. 200 #13-18, 22, 23, 24 (When making the line of best fit, also identify and describe the slope and y-intercept. You do not need to make an equation.
Khan Academy: I would complete the entire section titled Estimating with Trend Lines. It includes a lot of information and practice.

Estimating the line of best fit exerciseSal solves a problem where he has to estimate the line of best fit for a scatter plot.
