The measure of central tendency that describes the middle number in a data set. If there is more than 1 middle number, you find the average.
What is the median?
100
A data set's sum divided by the amount of numbers present.
What is the mean?
100
The three forms probabilities can be written as.
What are a decimal, fraction, and a percentage?
100
Events that are unaffected by each other.
What are independent events?
100
The median, mode, and mean considered measures of this.
What is central tendency?
200
A measure of variability that is found by subtracting the largest number from the smallest number in a data set.
What is range?
200
The mean of the data set {8, 7, 9, 6, 10}.
What is 8?
200
The probability of rolling a 5 when a die is rolled.
What is 1/6?
200
A type of event where the second is affected by the first.
What are dependent events?
200
The study or science of chances of an event occurring.
What is probability?
300
The number that shows the number in a data set that occurs most often.
What is mode?
300
The average of the data set {6,3,4,6,9,8}.
What is 6?
300
The probability of pulling a diamond from a deck of cards (number and certainty).
What is 13/52 (1/4), unlikely?
300
The probability of flipping tails and rolling a 1 or 2 on a die.
What is 2/12 (1/6)?
300
DAILY DOUBLE: The kind of probability are independent and dependent events related to.
What is compound probability (and)?
400
The median, mode, and range of the data set {11, 15, 12, 10, 10, 10, 13, 14, 13}
What are 12 (median), 10 (mode), and 5 (range)?
400
DAILY DOUBLE: The effect on the average maximum length of several whales when a whale with the length of 98 feet is added to the data set of {46, 53, 33, 53, 79}. (hint: increase/decrease/stay the same)
What is increase?
400
The probability of flipping heads or tails (number and certainty).
What is 1, certain?
400
The probability of pulling a red, and then a blue marble without replacing the first when a bag of marbles contains 7 blue, 5 purple, 13 red, and 5 orange marbles (number and type of event).
What is 91/870, dependent event?
400
A number that lies outside of the rest of the data set.
What is an outlier?
500
The median, mode, and range of the data set {55, 34, 35, 34, 57, 78}.
What are 45 (median), 34 (mode), and 44 (range)?
500
A situation when the mean is most useful to use.
What is the best central tendency to use when the data set has no outliers?
500
The probability of not rolling an even number on a die (number and certainty)?
What is 3/6 (1/2), equally likely?
500
The probability of pulling a red, and then a white when the first marble is returned to the jar when a jar contains 4 red, 3 white, and 5 blue (number and type of event).
