Graphical representation, uses rectangles

• Line graph

• Bar Graph

• Histogram

• Milligram

Answer explanation

Fun Fact: Histogram presents numerical data whereas bar graph shows categorical data.

Number of values that are free to vary after a sample statistics has been computed and they tell us the special curve to use when a distribution consists of a family.

• Degree Celsius

• Degree of Freedom

• Standard Deviation

• Mean

The spread of a group of number from the mean

• Variance

• Standard Numbers

• Standard Deviation

• Mean

Provides convenient forms of lengthy expressions, written before the solution.

• Mathematical notations

• Numbers

• Mathematical symbols

• None of the choices

Answer explanation

Remember: "a" and "b" are only z-score values.

Measures the average degree to which each point differs from mean
