Experimental Design

Question 1

What is Experimental Design?

Answer 1

• how participants are
• arranged/split up
• in different conditions

Question 2

What is a Repeated Measures Experimental Design?

Answer 2

-when participants experience both conditions

repeated because multiple measures

Question 3

What is an Independent Measures Experimental Design?

Answer 3

• > When particpants are randomly placed/seperated

- ->into two different cond.

Question 4

What is a matched pairs experimental design?

Answer 4

• > When participants are separated into diff. gs/ con.
• -> but are “matched up” or paired with a different participant
• -> who has sim. characteristics ( variables rel.)
• ->each group mirrors the other

Question 5

Explain the advantages of a Repeated Measures Experimental Design

Answer 5

• -> no ind. diff. between gs
  
  • -> bcus one same group
• -> Less time cons. 2 gather
  
  • ->fewer participants

Question 6

Explain the advantages of the Independent Measures Experimental Design?

Answer 6

• -> Avoids both F+ P order effects
• ->DCs less likely
  - ->only obs, one cond.

Question 7

Explain the advantages of a Matched Pairs Experimental Design?

Answer 7

• ->Reduces participant variables
  - ->same charact. in each group
• ->Both groups are easily comparable

Question 8

Explain the disadvantages of a Repeated Measures Experimental Design?

Answer 8

• ->High chance of order effects (P+F)
• -> High chance of demand charac,
  
  • ->experience both conditions
• ->High chance of attrition

Question 9

Explain the disadvantages of an Independent Measures Experimental Design

Answer 9

• ->diff. characteristics between each group

- -> Double ppl required than repeated measures

Question 10

Explain the disadvantages of a Matched Pairs Experimental Design?

Answer 10

• ->Time consuming
  
  • ->2 find sample able to be matched
• ->If participant drops out might have to remove other(lost data)
• ->Imp to match ALL charac.
