You can replicate the findings. 1 of 22 What is Validity ? How true is the causality of the behaviour, does the experi really explain what it claims to explain? 2 of 22 What is the independent variable ? Variable that is changed or controlled to test effect on the dependent variable 3 of 22 What is the dependent variable? The variable that is being tested and measured. 4 of 22 What does RV stand for and what is it? Random variables . RV's are other factors that could effect the outcome. 5 of 22 What is Confounding Variables? Factors that could affect the two IV levels differently- causes mistake in conclusion of what had affected DV 6 of 22 What is Extraneous Variable ? Factors that affect the DV, creating noise, resulting in unclear measurements. 7 of 22 In an un-ideal world, what are the 2 options of the cause of the variability ? 1) Variability in DV by the IV 2) Variability in DV caused by systematic or random error. 8 of 22 What is systematic error ? Affects the score of one condition differently to the other ( confounding variables) 9 of 22 What is random error ? It's spread randomly across the scores of both conditions ( Extraneous) 10 of 22 What are the two Experimental designs ? How do they differ? 1) Between participants design 2) Within participants design - Differ in the way participants take part in the IV conditions 11 of 22 When to use Between participants design? - Situations where participants cant be in both conditions , if its related to age/ gender etc. - Diff participant for each group 12 of 22 When to use Within participants design ? - Same participants can participate in both conditions. - Use when its hard to recruit participants 13 of 22 What is the FIELD experimental design? Iv is manipulated by the experimenter , in a real life setting like hospitals or schools 14 of 22 What is the NATURAL experimental design? -Iv changes occur naturally in a real life setting 15 of 22 What is categorical data? Scores from participants are placed in a category - eg race, gender ,educational level 16 of 22 What is continuous data? -Quantitive data that can be measured - Participants provide a score that can be any value on a measurement scale in use - eg temperature range 17 of 22 Reliability is.... Whether we can replicate the results - experimental effect is stable and cosistent 18 of 22 Validity is... Whether the experiment explains what it claims to explain - how true is the causality of the behavious 19 of 22 Confounding variable which causes systematic errors ... Affects the 2 Iv conditions differently , 20 of 22 Extraneous variable which causes random errors ... are factors that may affect the DV in some way 21 of 22 Extreneous and confounding variables can be restricted by... - contorlling or manipulating the variables - randomization - Counterbalance 22 of 22
