Statistics: Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real-life studies.
-
The standard error is a statistical term that measures the accuracy with which a sample distribution represents a population by using standard deviation.
-
Measure of Spread:A measure of spread, sometimes also called a measure of dispersion, is used to describe the variability in a sample or population.
-
Parameter: In math, a parameter is something in an equation that is passed on in an equation
-
A measure of central tendency is a summary statistic that represents the center point or typical value of a dataset.

-
Population: A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from.

-
The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average
-
-
In statistics, an outlier is a data point that differs significantly from other observations
-
The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance
-
Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate )
