Inferential statistics
Descriptive statistics - ANSWER Helps to explain characteristics of variables
Describes summaries, and synthesizes collected data
Collection and presentation of data that explain characteristics of variables:
frequencies, measures of central tendency
Inferential statistics - ANSWER Helps to explain relationships among the
phenomenon of interest
Using frequencies to Describe Samples - ANSWER Information about the
frequency, or how often, a variable is found to occur
Presented as % or P
Ex: if 12/64 students failed the rest, what is the percentage of failed students?
Frequencies are - ANSWER grouped and ungrouped
Ungrouped data - ANSWER used to present nominal and ordinal data
Grouped data - ANSWER used to present interval and ratio data
Measures of Central Tendency - ANSWER measures that provide information about
the typical case in the data (mean, median, mode)
mean & median describe continuous level data
The mode can describe both continuous and categorical level data
Mean - ANSWER Mathematical average calculated by adding all values and then
dividing them by the total numbers of values
The best and most commonly used measure
Greatly affected by outliers
When data have no outliers, researchers prefer to report the mean
, Median - ANSWER The point at the center of a data set
Divides the data into two halves
Best measure if there are extreme values (outliers)
Formula: (n+1) divided by 2
Mode - ANSWER The most frequently occurring value in a data set
Not affected by any extremes in data
Amodal, unimodal, bimodal
Amodal - ANSWER without a mode
Unimodal - ANSWER with one mode
Bimodal - ANSWER with two modes
Distribution Patterns - ANSWER Normal distributions: Symmetrical shapes
Measures of central tendencies are used to define distributional patterns
When data is symmetrical, the mean, median, and mode are equal- data
representation with a distinctive bell
-shaped curve, symmetrical around the mean
-ex: intelligence, height
When data is not normally distributed - ANSWER Data is asymmetrical or "skewed"
Positively skewed distribution - ANSWER a distribution pattern when the man is
greater than the median and the mode
-ex: most students failed the test but one did very well
High scores positively affect the mean
Tail goes to the right
Negatively skewed distribution - ANSWER a distribution pattern when the mean is
less than the median and the mode
-ex: Many students did great on the midterm but one students got a very low score
Low scores negatively affected the mean
Tail goes to the left
Measures of Variability - ANSWER provide information regarding how different the
data are within a set
