Covariance
Covariance measures how two variables vary together.
Definition · Example · CSE Use →Linear Regression
Linear regression models a response as a linear function of one or more predictors.
Definition · Example · CSE Use →Mean
The arithmetic average found by adding values and dividing by the number of values.
Definition · Example · CSE Use →Median
The median is the middle value after data are sorted, or the average of the two middle values for an even count.
Definition · Example · CSE Use →Mode
The mode is the value that occurs most frequently in a dataset.
Definition · Example · CSE Use →Normal Distribution
The normal distribution is a symmetric bell-shaped continuous probability distribution defined by its mean and variance.
Definition · Example · CSE Use →Percentile
A percentile indicates the value below which a given percentage of observations fall.
Definition · Example · CSE Use →Population
A population is the complete collection of individuals, measurements or outcomes of interest.
Definition · Example · CSE Use →Quartile
Quartiles divide ordered data into four parts.
Definition · Example · CSE Use →Sample
A sample is a subset of a population used to estimate or study the whole population.
Definition · Example · CSE Use →Standard Deviation
Standard deviation is the square root of variance and measures spread in the original units.
Definition · Example · CSE Use →Statistical Range
The statistical range is the difference between the maximum and minimum values in a dataset.
Definition · Example · CSE Use →Variance
Variance measures the average squared deviation of values from their mean.
Definition · Example · CSE Use →Z-Score
A z-score states how many standard deviations a value lies above or below the mean.
