Graphs
a statistical chart consisting of data points plotted on a fairly simple scale, typically using filled in circles
Dot plot
The smallest data point
Minimum
variable that can take on one of a limited, and usually fixed, number of possible values are what type of data?
Categorical
Skewed or symmetrical refers to
Shape
The distribution of values of a variable among all individuals described in a table
Marginal Distribution
Bar Graph
The value under which 25% of data points are found when they are arranged in increasing order.
Q1 of the First Quartile
When the data has an infinite number of numerical possibilities it is
Quantitative
Q1- (IQR1.5) AND Q3+ (IQR1.5) find the
Outliers
Describes two categorical variables
Two-way table
a type of graph in which a circle is divided into sectors that each represent a proportion of the whole.
Pie Chart
denoting or relating to a value or quantity lying at the midpoint of a frequency distribution of observed values or quantities, such that there is an equal probability of falling above or below it.
Median
a quantity which during a calculation is assumed to vary or be capable of varying in value.
A Variable
Median or Mean are the
Center
When each % is rounded to the nearest 1/10 this can lead to
Roundoff errors
A way/graph to split quantitative data into leaves and stems
Stemplot
the value under which 75% of data points are found when arranged in increasing order.
What the data is describing/what is being surveyed
Individuals
Spread
The value of a variable that among individuals has a specific value of another variable
Conditional Distribution
Histogram
The largest data point
Maximum
Describes what values the variable takes and how often it takes them
Distribution
Q3-Q1 is the
IQR or Interquartile Range
Specific Values of one variable tend to occur in common with specific values of another variable
Association
