Question | Answer |
---|---|
compound probability | the probability of two or more events occurring |
dependent even | events in which the outcome of one event does affect the outcome of the other event or events. |
experimental probability | the ratio of the number of favorable results to the total number of trials in a probability experiment; is based on what DOES happen in an experiment |
independent event | two or more events in which the outcome of one event does not affect the outcome of the other event |
random | an outcome of an event is equally likely to occur compared to another outcome. |
sample space | the set of all possible outcomes of a probability event |
simulation | an experiment designed to act out a given situation |
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 |
bias | a statistical sampling or testing error caused by systematically favoring some outcomes over others |
box and whisker plot | a diagram that summarizes data using the median, the upper and lower quartiles, and the extreme values. |
inference | refers to drawing a conclusion from data |
outlier | a piece or pieces of data that lie out from the rest of the data (high or low) that can skew (affect) the mean; extreme data that is more than 1.5 more times the interquartile range from the upper or lower quartiles |
quartile | values that divide a set of data into four equal parts |
sample | randomly selected group chosen for the purpose of collecting data |
scatter plot | compares two sets of data to see relationships |
trend | a general direction either upward or downward is called |
trend line | in a scatterplot, a line that closely fits the data points. |
validity | in an experiment, there were no biases or unjust sampling when collecting the data |
