Four important properties that are at least a part of any set of measurements |
*The central value (Central Tendency) *The spread about the center (Variability) *The symmetry around the center (Skewness) *The general shape of the distribution (Kurtosis) |
|
|
Numerical Descriptive Statistics utilize... |
*Central Tendency *Variability *Skewness *Kurtosis |
|
|
Define ASPATIAL (Nnumerical Statistics) |
Nothing to do with the locations of the observations, only concerned with distribution in attribute space. |
|
|
List three ways to identify the center... (Central Tendency) |
*Mean *Median *Mode |
|
|
Define MEAN |
The mean is the sum of all values of X from the first observation to the n'th observation, all divided by n |
|
|
Define MEDIAN |
The value that has an equal number of larger and smaller values The midpoint of the data. (If n is odd, pick the middle data point. If n is even, take the average of the two middle values) |
|
|
Define MODE |
*Is the most frequent value *A variable can have both more than one mode or no mode at all |
