Dependent variable

Confounding variable
Demand characteristics
When the participants try to make sense of the experiment and acts accordingly to support the aim of the experiment
Ecological validity
How well a test reflects real life situations and how the results ca be generalised
Temporal Validity
refers to how over time things change that can affect a experiment
External Validity
Internal Validity
Mundane Realism
Quantitative data
Data that is numerical or any variable that can be counted
Qualitative
Non-numerical data that relates to data expressed in words
What are the 4 types of Quantitative data?
Ordinal data
Nominal data
Ratio data
Interval data
Ordinal data
Data that exist in categories with a natural order
Nominal data
Data that exist in categories with no natural order
Ratio data
Data with number values that can’t go below zero,for which we can tell exactly how much bigger one number is than another
Interval data
Data with number values that can go below 0 for which we can tell exactly how much bigger one number is than other
