I need to investigate whether perception of intelligence is influenced by a person's facial expression and/ or gender. Some photos were of males; others were of females, and within each of those groups, some were smiling whereas others had neutral facial expressions. All 12 participants were shown the same photo set. This means each participant judged every condition - male smiling; male neutral; female smiling; female neutral.

	Smiling pictures	Neutral pictures
	Male photos	Female photos	Male photos	Female photos
Participant A	8.7	8.2	8.5	9.0
Participant B	9.1	8.0	9.0	8.5
Participant C	8.3	9.0	8.3	8.4
Participant D	9.5	8.8	9.4	9.2
Participant E	9.0	8.2	8.9	8.8
Participant F	7.7	7.0	7.8	7.5
Participant G	8.6	8.8	8.5	8.0
Participant H	8.5	7.3	8.4	7.7
Participant I	9.1	6.5	9.2	6.5
Participant J	9.2	8.0	9.1	8.1
Participant K	8.2	8.1	8.1	8.3
Participant L	8.0	7.5	7.9	7.9

1. How do I find what the factors are in this scenario and which are BS or WS?
2. What is the relevant statistical output I need to show?
3. What graph would I create to represent?
4. How do I Present the results in writing?
