A
The number that appears most frequently in a set of numbers.
Mode
The difference between greatest and the least value in a set of numbers.
Range
It is the number of ways a particular set can be arranged.
Permutations
How likely something is to happen.
Probability
It is the average of a group of numbers.
Mean
It is the middle number in a set of ordered numbers.
Median
The closer the number is to 0.
Weakest Correlation
It is a term used to compare two or more numbers.
Ratio
The percent change of a variable over time.
Growth rate
It is an outcome of a random experiment.
Sample
It is used to measure how strong a relationship is between two variables.
Correlation Coefficients
The closer the number is to -1 and 1.
Strongest Correlation
It represents the dependent variable.
y-axis
Splits each data value into a "stem" (the first digit) and a "leaf" (usually the last digit)
Stem-and-Leaf Plot
Places dots along an axis for each case in the data.
Dot Plot
It represents the independent variable.
x-axis
Comparing two sets of data values for a single quantitative variable.
Side-by-Side stem-and-leaf
It divides up a set of data values into equal-width bins (bars), where the height of each bin shows the count or proportion of data values that fall within the interval that the width of the bin covers.
