Why do we need a theory? |
1. It provides a framework for analysis; 2. It provides an efficient method for field development; and 3. It provides clear explanations for the pragmatic world. |
3 things |
|
|
What are Constructs? |
Abstract expression of the ideas and objects that is known as the building blocks of theory |
Has to do with theory |
|
|
What are the different Types of variables? |
Independent, dependent, controlled, mediating, moderating, confounding |
|
|
|
What are Independent variables? |
A variable that is independent and doesn’t depend/isn’t affected by something else |
|
|
|
What Is a Dependent variable? |
A variable that is dependent a and/or changed depending on what the dependent variable is/does |
|
|
|
What is a Control variable? |
A variable that is controlled |
|
|
|
What is a MEDIATING variable? |
A mediating variable explains why two things are related. |
|
|
|
What is a MODERATING variable? |
A moderating variable is a variable that affects the strength of the relationship between two variables. |
|
|
|
What is a CONFOUNDING variable? |
A confounding variable is a variable that correlates and explains both the independent variable and dependent variable. |
|
|
|
What are Latent Variable and Manifest variables? |
Latent Variable: Variables that are not directly observed Manifest variable: Variables that are directly observed |
|
|
|
What is Primary data? |
The exact information needed/wanted is obtained by YOU find it yourself/ do research yourself |
|
|
|
What is Secondary data? |
You find it from a source where SOMEONE ELSE has found/researched for you, you just research for their info. |
|
|
|
What is Arithmetic Mean? |
Arithmetic mean (add all together and divide by the # of total ‘sample’ - problem is it doesn’t work well with percentage) |
|
|
|
What’s is geometric mean? |
Geometric mean (geometric average, the end route of the product of data - best used when dealing with a rate of growth) |
|
|
|
What is weighted mean? |
Weighted Mean (weights the important data of the less important data) |
|
|
|
What is trimmed mean? |
Trimmed Mean (the average after a percentage of the highest and lowest values are removed) |
|
|
|
Why is interquartile mean? |
Interquartile mean (trimmed mean based on data within the interquartile range (25%-75%) |
|
|
|
What is winsoeized mean? |
Winsorized mean (means where extreme values are replaced by values closer to the median) |
|
|
|
What is mode? |
Mode (Frequent and Fashionable - things in the data set that appear more often/most often) |
|
|
|
What is dispersion/standard deviation? |
Dispersion/Standard Deviation: a way to calculated and indicate the extent of deviation for a group as a whole - shows the frequency of the numbers, and how close data is to the mean |
|
|
|
What is Median? |
Median - the middle score for a set of data that has been arranged in order of magnitude. (examples: the very middle of everything from highest to lowest) |
|
|
|
What is nominal level of measurement? |
Nominal: Each value has a unique meaning. examples: gender, sports, amenities - check for IDENTITY |
|
|
|
What is ordinal level of measurement? |
Ordinal: Values have an ordered relationship, but the space and values between them are larger, some are smaller. Examples: heat scale of food, sizes of drinks - check for MAGNITUDE |
|
|
|
What is interval measurement? |
Interval: Units along a scale, and the space between them is equal. There may be a 0, but the 0 is not absolute. (0 doesn’t = nothing) example: temperature - check for EQUAL INTERVALS |
|
|
|
What is ratio measurement? |
Ratio: Satisfies identity, magnitude, equal intervals, and absolute zero. Has an absolute 0, and the intervals in between are equal. Examples: weight, items you can own, speed - check for ABSOLUTE ZERO |
|
|
|
What are the steps in screening data? |
Fix or remove incorrect data Check for outliers Check for unusual cases Check for duplicate cases |

- omitting baseline - manipulating X & Y axis -cherry picking data -using the wrong graph -going against convention |
