Variable
A quantity that may be changed according to the mathematical problem.
categorical Data (Variable)
Types of Data–which groups may be divided into groups–
Quantitative Data (Variable):
one that can be measured and assigned a numerical value
Discrete variable
Has a center # of particles values and nothing else
Continues variables

distribution
describes how values are distributed for a field
Frequency table
A way of summarizing a set of data
Relative Frequency table
A two way relative table shows the proportion or percentage of each entry out of the total # or data points
Bar Graphs
A chart or graph that presents categorical Data with rectangular bars with heights or lengths proportional to the values that they represent
Pie chart
A type of graph representing data in a circular form, with each slice of the circle
Stemplot
A way to plot data where the data is split into stems (the largest value) and leaves (the smallest digits)
Histogram
a type of chart that shows the frequency distribution of data points across a continuous range of numerical values.
Time-Series
A line graph that shows data such as measurements, sales or frequencies over a given time period
Association
Information about the value of one variable provides information about the value of the other variable
Causation
Indicates that one event Is the result of the occurrence of the other event
Mean
A measure of central tendency of the probability distribution along median and mode
Median
The # in a sequences of #s
Range
The difference between the highest and the lowest values
