Question | Answer |
---|---|
Complementary Events | Two Events are complements if the sum of their probabilities is 1. |
Experimental Probability | The ratio of the number of a favorable result to the total number of trials in a probability experiment. |
Favorable outcome | The desirable outcome |
Frequency Table | A table that lists items and uses tally marks to collect data and show the number of times they occur |
Interval | The equal parts of a scale is divided into, on a graph. |
Line Plot | A number line used to show frequency of data |
Mean | The mathematical average of the data; found by finding the sum of all of the data and dividing by the number of data pieces |
Measure of Central Tendency | Numbers or pieces of data that can represent or summarize a whole set of data, such as mean, median, and mode. |
Sample Space | The set of all possible outcomes of a probability event |
Scale | The set of numbers used to label an axis when graphing; must include the least and greatest numbers in a set. |
Simple Event | A probability even that consists of exactly one outcome. |
Stem-and-leaf plot | A display of numerical data in which each piece of the data is separated into two numbers based on place value and placed in columns of a T-chart. |
Theoretical Probability | The ratio of the number of favorable outcomes to the total number of possible outcomes;is based on what should happen under perfect circumstances. |
Tree Diagram | A visual representation that shows all possible outcomes in a probability even. |
