Math Vocabulary Tedt 3

A ————— divides a sorted data set into 4 equal parts. So that each part represents 1/4.

Box plot

Data that are based on "qualities" such as color, taste, or texture, rather then measurements Is called ——————————

Categorical data ( quantitative )

——— is when one event causes another to happen.

Causation

Data that can take almost any numeric value over a continuous range is known as ——————-

Continuous data

A statistical relationship between two or more data sets is known as ————.

Correlation

Often known as r; the correlation coefficient is a measure of the strength of direction of the linear association between two quantitative variables

Correlation coefficient

———————- is Data that contains a finite number of possible values.

Discrete data

The ———— states that for a normal distribution, nearly all of the data will fall within 3 standard deviations of the mean (68% within one, 95% within two, and 99.7% within three standard deviations)

Emperical rule

The middle 50% of the data set, also known as the IQR is the ————-

Interquartile Range

The ——— is the average of the data values.

Mean

The number in the middle when the data in a set are ordered from least to greatest is called the ——-

Median

The most frequently occurring value in a data set is called the ——-.

Mode

In —————— the mean, median, and mode of the data are equivalent and the graph is often a bell curve

Normal distribution

An extreme value in a data set that is very distant from the others is called a ————

Outlier

——————— is data that can be measured and recorded numerically.

Quantitive data

———-is data that have a long tail on one side or the other; a data set in which the mean is greater or less than the median.

Skewed data

The ——- describes the variance in the data.

Spread

The typical distance of the data values from the mean is ———————

Standard deviation

The science of collecting, organizing, and analyzing data is known as ————.
