Vocabulary: Summarize and Describe Distributions

Mean

• The average of a set of numbers, calculated by dividing the sum of all values by the number of values.

• The middle value in a set of numbers when arranged in order.

• The value that occurs most frequently in a set of numbers.

• The difference between the highest and lowest values in a set of numbers.

Outlier

• A data point that is significantly different from other data points in a dataset.

• A data point that is exactly the same as other data points in a dataset.

• A data point that is the average of all data points in a dataset.

• A data point that is the most frequently occurring in a dataset.

Frequency

• The number of times a data point appears in a dataset.

• The average value of a dataset.

• The range of values in a dataset.

• The total number of data points in a dataset.

Interquartile range

• 25% of the data, which lies between the lower and upper quartiles.

• 50% of the data, which lies between the lower and upper quartiles.

• Randomly selected data points used for analysis.

• Categories that represent different data types.

• Single data points plotted on a graph.

Bar graph

• A graph that represents data using vertical or horizontal bars.

• A type of chart that uses lines to connect data points.

• A diagram that shows the relationship between two variables.

• A visual representation of data using pie slices.

Standard deviation

• A measure of the amount of variation or dispersion in a set of values.

• A method for calculating the mean of a dataset.

• A technique used to visualize data distributions.

• A statistical test for hypothesis testing.

Mode

• The average value of a dataset.

• The value that appears most frequently in a dataset.

• The middle value when the data is sorted.

• The range of values in a dataset.

Pie chart

• A circular graph divided into slices to illustrate numerical proportions.
