Chapter 11: Statistics
Exponential Model Given the following data, find the equation of the exponential model. Years after 1970Population (in millions)
Correlation
Mean Find the mean from the frequency table: ScoreFrequency
Standard Deviation Standard deviation measures the “spread” or “variability” of the data. A small standard deviation indicates data that are all very similar. A large standard deviation indicates data that are very different.
Normal Distribution Remember the 68 – 95 – 99.7% rule
Normal Distribution Test scores were normally distributed with a mean of 100 and standard deviation of 10. What percent of students scored between an 80 and 120?
Types of Studies Survey: a questionnaire given to a sample of individuals. Observational Study: gather data on a topic without manipulating any variable Experiment: purposefully manipulate one variable to examine its effect on another variable
Types of Studies Categorize each type of study: A college sends a feedback postcard to students who recently attended an open house. A researcher compares the SAT scores of students taking Latin with students not taking Latin. The number of heart attacks is compared when one group of individuals are assigned to take an aspirin a day while another group does not not.
Chapter 13: Trigonometry SOH-CAH-TOA Given the triangle, find the value of the three trig functions.
Angle of Elevation or Depression A road rises 10 feet over a horizontal distance of 80 ft. Find the angle of elevation of the road.

Exact Value or Unit Circle
Exact Value of Sin, Cos, Tan Find the reference angle. (Convert to degrees if necessary.) Use the table of exact values. Decide if the function should be positive or negative by using A-S-T-C.
