In statistics, the standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values
bar graph
A bar chart or bar graph is a chart that presents grouped data with rectangular bars with lengths proportional to the values that they represent
scatter plot
A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data

Scientific notation
Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form
significant figure
The significant figures of a number are digits that carry meaning contributing to its measurement resolution
pie chart
A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion
A table is a collection of related data held in a structured format within a database
Internal validity
In scientific research, internal validity is the extent to which a causal conclusion based on a study is warranted, which is determined by the degree to which a study minimizes systematic error
