Measures of Center & Variation
If you randomly pick a card from a deck of 52, what is the probability that you will pick a RED KING?
1/26
I am a graph created by plotting 2 pieces of quantitative data as my x and y coordinates. You may want to find the STRENGTH and DIRECTION of my correlation by solving for r in your calculator. What kind of graph am I?
Scatter Plot
A bag contains 12 balls; 3 red, 5 blue, and 5 yellow. What is the probability of selecting a blue ball at random?

If you randomly select a card from a deck of 52, what is the probability of selecting a black card?

I am a graph created by finding the frequency of given categories of quantitative data. The height of each of the bars (which always touch) represents the frequency of a category. What kind of graph am I?
Histogram
A spinner has 4 equal pieces to it, labeled 1, 2, 3, or 4. What are the odds that you will spin a 2 first and a 3 second?
1/8
On a TRUE/FALSE test, you guess for 3 questions. What is the probability you get those 3 questions correct?
1/8
The EMPIRICAL RULE divides the normal curve by standard deviations from which measure of center?
MEAN
On a standard six-sided die, what is the probability of rolling a number less than 3?
1/3
I am a graph created by finding the frequency of qualitative data. The frequency is converted to a percent so it's easy to compare my "slices" which represent each category. What kind of graph am I?
Circle Graph
You are taking a multiple choice test, with each question having 4 answers. What is the probability of answering 5 questions correctly?
1/1024
What is the correlation between amount of exercise and body weight?
Negative
A 2008 survey of high school seniors found that they work an average of 12 hours a week outside of school, normally distributed with a standard deviation of 2 hours. Using the Empirical Rule what PERCENT of students work between 10 and 14 hours outside of work?
68%
I am a graph created by "stacking" data points above a number line. I am a great graph to use when finding a mode of a data set, since you'll just look for the tallest tower. What kind of graph am I?
Dot Plot
A cooler has 8 cans of soda; 3 cokes, 3 sprites, and 2 root beers. You reach into the cooler to get your friend a soda, give it to them, then get one for yourself. What is the probability your friend AND YOU will get a Coke?
3/28
You are taking a multiple choice test, all with 4 possible answers. If you knew that two of the answers were incorrect, what is the probability that you will guess the right answer?

Students were asked how many hours they work outside of school in a week. 5 students worked 10 hours, 6 students worked 12 hours, 4 students worked 14 hours, 2 students worked 16 hours, 2 students worked 18 hours, and 1 student worked 20 hours. Find the mean, median, and mode of this data set.
MEAN : 13.3
MEDIAN : 12
MODE : 12
You are rolling a six-sided die three times. What is the probability of rolling a 2 on the first roll and not a 2 on the second and third rolls?
25/216
I am a graph created by finding the five number summary of a set of data. These 5 data values are plotted above a number line and the width of my middle section is known as the Interquartile Range (IQR). What kind of graph am I?
