Lesson 13 Flashcards
It is computed to determine the proportion of a part to a whole, such as given the number of respondents
Percentage
Used to determine the order of decreasing or increasing magnitude of variables
Ranking
The overall average or responses/perceptions of the study respondents
Weighted mean
The sum of the scores and its product
Weighted mean
What are the measures of central tendency
Arithmetic mean
Median
Mode
Another term for average weighted mean
Arithmetic mean
Describes the central tendency of the given criteria or variables
Arithmetic mean or average weighted mean
All numbers are added together and divided by the number of numbers in a series
Arithmetic mean
The central position
Median
Arranges the ratings in an array from highest to lowest or vice versa and pick the central
Median
The score which has the most number of observation or responses
Mode
The ‘MOST FREQUENTLY occurring values in a series of numbers’ where more than one value equally shares the highest number of frequencies
Mode
to determine the probability that the NULL HYPOTHESIS IS UNTRUE
Inferential statistics
Indicate the chance that RESEARCHERS ARE WRONG in rejecting the null hypothesis
Level of significance
The level of significance is also called as
Level of probability
The research prediction that is tested
Research hypothesis
The statement of NO DIFFERENCE between the means of two population
Null hypothesis
Technical necessity of inferential statistics
Null hypothesis
It is made when a researcher REJECTS THE NULL hypothesis when it is TRUE
Type I error
When a researcher accepts the null hypothesis when it is false
Type II error
This is used when the researcher can ‘assume that the population values are normally distributed’, variances are equal,,,,
Parametric tests
The ‘most common statistical procedure for determining the level of significance’ between two means is compared
T-test
Similar to t test, used when there are more than two groups being compared
anova / analysis of variance
An extension of the t-test and allows a researcher to examine differences in all population
anova
