Probability and Data
This is for our unit on probability and data analysis
Question | Answer |
---|---|
Possible results of a probability event. | Outcomes |
One outcome or a collection of outcomes. | Simple Event |
The ratio of the number of favorable outcomes to the number of possible outcomes. | Probability |
The set of all possible outcomes. | Sample Space |
What should occur in a probability experiment. | Theoretical Probability |
What actually occurs in a probability experiment. | Experimental Probability |
A diagram used to show the total number of possible outcomes. | Tree Diagram |
If two independent events occur in succession, their individual total number of outcomes can be multiplied to give their combined total number of outcomes. | Fundamental Counting Principle |
An arrangement or listing in which order is important. | Permutation |
The expression n factorial (n!) is the product of all counting numbers beginning with n and counting backwards to 1. | Factorial |
An arrangement or listing in which order is not important. | Combination |
The sum of the data divided by the number of items in the data set, also called the average. | Mean |
In a set of data, the middle number of the ordered data, or the mean of the two middle numbers. | Median |
The number or numbers that occur most often in a set of data. | Mode |
The smallest value in a set of data. | Minimum |
The largest value in a set of data. | Maximum |
The difference between the minimum and maximum in a set of data. | Range |
A diagram that divides a set of data into four parts using the median and quartiles. A box is drawn around the quartile values and whiskers extend from the quartiles to the minimum and maximum data points. | Box and Whisker Plot |
The median of the lower half of a set of data. | Lower Quartile |
The median of the upper half of a set of data. | Upper Quartile |
Data that are more than 1.5 times the interquartile range from the quartiles. | Outliers |
Indicates the number of values in each interval in a histogram. | Frequency |
Uses bars to display numerical data that have been organized into equal intervals. | Histogram |
