Types of Experimental Designs

Completely Randomized Design assigns units to groups randomly.

• True

• False

In Completely Randomized Design, each group recieve ____ treatment/s.

• the same

• different

In Randomized Block Design, a reasercher assign participants...

• randomly

• based on a specific chacteristic

Each block recieves...

• the same treatments

• different treatments

Blocking variable in this example is...

• group size

• type of treatment

• gender

In Matched Pairs Design...

• treatment order is random

• we are only comparing two treatments by using the same (or similar) experimental units

• each experimental unit recieves the same treatments

• all answers are correct

We use similar experimental units...

• when we cannot use the same experimental units

• always when we conduct Matched Pairs Design

• neither is true
