Statistics
The study of the collection and analysis
of numerical data; the numerical facts or
data itself (mean, median, mode, range,
standard deviation, etc.).
Many different types of statistics can be found and
calculated, too numerous to list here.
Measures of Central Tendency
The type of statistics used to measure
the ‘center’ of a data set - Mean,
Median, or Mode
Depends – use the method for each term
Mean
The average of the data
Sum all of the data values and divide by the
number of data values in the set
Median
The middle value
Arrange the data from least to greatest or greatest
to least and find the center value – cross off or
count an equal number from each end. If there are
two middle values, their average is the median.
Mode
The value that occurs most often
Count how many times each value appears in the
list. The one that occurs most often is the mode. It
is possible to have more than one mode. If no
number appears more than once, there is no mode.
Range
The difference between the highest
value and the lowest value
Subtract the lowest value from the largest value
