Ordered Pairs
Tells the locations of each point & which quadrant they fall in.
Slope-intercept form
y=mx+b
Slope Formula
y2-y1/x2-x1
Quantitive data
also called numerical data, consists of data values that are numerical, representing
quantities that can be counted or measured. (Dot plot, stem plot, box plot, and
histogram)
Histogram
provides continuous data
Box Plot
shows the 5 star summary
Stem Plot
requires a small data set and shows exact values
Dot plot
Each dot represents a data value and is good for repeated data
explanatory variable
a variable that we think explains or causes changes in the response variable
response variable
the affected variable
measures of center
a single measure that represents the center of the data set (mean, median, and mode)
measures of spread
a single measure that represents the spread of the data set (standard deviation, range,
and IQR)
Categorical data
also called qualitative data, consists of data that are groups, such as names or labels,
and are not necessarily numerical examples (pie chart & bar chart)
Two-way table (contingency table)
- the rows show the categories of one variable, & the column shows the categories of
the other variable
- C -----> C
Side by Side Plots
- can be horizontal or vertical, so either variable can be displayed on the x & y axis
- C ----> Q
Scatterplots
- X & Y axis determine the location of a dot on a scatterplot
- Q ----> Q
Categorical -----> Quantitative
