These flashcards cover key vocabulary and concepts from the AP Statistics semester 1 material, providing definitions and explanations to aid student understanding and retention.

Skewed Right

A distribution that has a tail on the right side, indicating that more data points are concentrated on the left side.

Median

The value separating the higher half from the lower half of a data sample.

Histogram

A graphical representation of the distribution of numerical data using bars, where the height of each bar represents the frequency of data points within a specific interval.

Z-score

A statistical measurement that describes a value's relation to the mean of a group of values, expressed in terms of standard deviations.

Percentile

A measure used in statistics indicating the value below which a given percentage of observations in a group falls.

Normal Distribution

A probability distribution that is symmetric about the mean, meaning most of the observations cluster around the central peak and form a bell curve.

Explanatory Variable

The independent variable that is manipulated in an experiment to observe its effect on the response variable.

Regression Line

A line that models the relationship between two variables by minimizing the distances from each point to the line.

Box Office Success

A measure of how much revenue a film generates, often compared to its production budget.

Double Blind Experiment

An experimental procedure where both the participants and the experimenters do not know who is receiving a particular treatment, reducing bias.

Expected Value

The predicted average outcome of a random variable, calculated as the sum of all possible values each multiplied by their probability.
