Time order of occurrence Concomitant variation Absence of other causal factors
4
One thing consistently happens before the other Light switching? Service quality and loyalty? Liking K-pop and Liking K-food? Demand and lower price? Unemployment and financial crisis?
5
The variables ‘move’ together predictably.
8
One of the strengths of experimental design is it’s ability to exclude these ‘confounding variables’
9
Experimental design is a planned interference in the natural order of events. There is more than just observation or measurement. A selected condition or a change (treatment) is introduced. Observations or measurements are planned to illuminate the effect of any change in conditions
10
You want to isolate a cause-effect relationship with high degree of certainty You cannot measure the independent variable You want to see if different treatments lead to different results
11
Nominal/Categorical Ordinal Interval Ratio Gender: Male (1) and Female (2) What is your age: …… What is your age: (1) under 18 (2) 19-25 (3)26-40 (4) over 40 How much do you like this product? 1 (strongly dislike) ……………7 (strongly like) What is your height: …… Did you take the (1) blue or (2) red pill? League rankings:
12
90% of U.G research projects boils down to: - Measure IV - Measure DV - Find out Correlation/Regression Value i.e how well they ‘move together’ upwards, downwards, or inversely
13
The effect of satisfaction (x) to loyalty (y) The effect of convenience (x1) and cost perception (x2) to adoption The effect of liking Kpop (x1) and moderating effect of gender (m1) to liking Korean brands (y) The effect of company reputation to its appeal for future employees
14
Video lectures -> student grades ‘limited stock’ sales strategy -> willingness to buy Red vs Orange ‘buy’ button on website -> click- through Company CSR -> consumer goodwill
15
Effect of temperature towards aggressive tendencies Effect of lecture time towards student engagement Effect of mood towards helpfulness Effect of feeling powerful towards kindness for others Effect of giving a backstory towards preference of a photograph
18
A hypothesis A scenario A control group (guarding against placebo effect) A lot of readings of literature A lot of trial and errors
19
Please imagine yourself going through this scenario (condition A) You are walking around the shop wanting to buy a bluray player. After checking the ones you want, you see the booth that displays a prominent Korean brand bluray players, and they were having a sale. It’s a limited- stock item selling for only RM399. How likely are you going to buy this? (1-7) (condition B)You are walking around the shop wanting to buy a bluray player. After checking the ones you want, you see the booth that displays a prominent Korean brand bluray players, and it’s priced at RM399. How likely are you going to buy this? (1-7) If we’re using another method instead of experiment, how would you design it?
20
Sales tactic Intention to buy Regular sale Intention to buy Limited stock sale OR?
21
Add in country and price as a manipulated variable “You are walking around the shop wanting to buy a bluray player. After checking the ones you want, you see the booth that displays a prominent Japanese brand bluray players, and they were having a sale. It’s a limited- stock item selling for only RM399.” “You are walking around the shop wanting to buy a bluray player. After checking the ones you want, you see the booth that displays a prominent Korean brand bluray players, and they were having a sale. It’s priced at RM599.”

26
Experiments have the highest claim to determine causality Relatively easy to process (statistically) Very convenient to adjust/manipulate variables via scenarios High usefulness in the marketing context Situations are ‘artificial’ Subject to human error/bias Sacrifices external validity (generalizable) for internal validity (accuracy in measurement) Gets very complicated very fast
27
Control group specifics Manipulation checks Reliability issues ANOVA/T-test procedures Controlling for nuisance/confounding variable via ANCOVA Ethical concerns Presenting the results
