Describing distributions
What is the distribution description that is based on how a graph looks? Ex: skewed left, skewed right, symmetric, bimodel, etc.
Shape
the ratio between the frequency of a row total or column total to the total frequency of the data
Marginal relative frequency
the data with the lowest value
Minimum
a graphical representation of information using bars extending to different heights
Bar graph
a technique used to classify either discrete or continuous variables
Stem and leaf plot
What is the distribution description that calculates abnormal values?
Outliers
The proportion of observations that fall into a specific combination of two categorical variables
Combined Joint relative frequency
the value under which 25% of data points are found
Q1 or Quartile one
circular statistical graphic which is divided into slices to illustrate numerical proportion
Pie chart
a graph that shows the frequency of numerical data using rectangles
Histogram
What is the distribution description that helps with location?
Centers
dividing a joint relative frequency by its related marginal relative frequency
Conditional relative frequency
the middle number in a sorted ascending or descending list of numbers
Median
a special type of stacked bar graph
Segmented bar graph
shows how the data is distributed and it also shows any outliers
Box plot
What is the distribution description that tells you how far the points are away from each other?
Variability
the value under which 75% of data points are found when arranged in increasing order
Q3 Or Quartile three
(Sometimes catagorical) used to represent any data in the form of dots or small circles on a line
Dot plot
(Sometimes quantitative) used to represent any data in the form of dots or small circles on a line
Dot plot
the data with the highest value
Maximum
