photographs will then be labelled using M1 to M10 for the male photographs and F1 to F10 for the female photographs. Each number will coincide with each member of the couples. I will also need a 10-point scale to rate the photographs. This should be the same for every participant (see appendix).
Standardised Procedure
In order to reduce researcher bias I used standardised briefing, I gave strict instructions to every participant and I continued the research only after consent was given by the participant.
Both female and male participants were shown the photographs of both partners but were asked to only rate the partner of the opposite sex on a scale of 1-10on the given scoring sheet.
Ethics
Due to a minor deception as the aim of the study was not told beforehand only partially informed consent could be sought. Participants were told what the task required them to do and they had the right to withdraw. This level of deception was necessary to prevent demand characteristics and it did not cause harm to the participants. It was dealt with a full debrief at the end, which included showing the participants photographs of the couples.

Spearman’s Rho correlation analysis:
I will use the Spearman’s Rho correlation analysis because it will give me a specific number and allow me to identify whether I have proved the matching hypothesis. I will do this by identifying whether I have reached or achieved a higher level of the statistical significance, for this investigation the statistical significance is 0.5.
Spearman’s Rho Procedure:
1. Rank the Mean ratings for the Female and male members of the couples
2. calculate the difference between each couple (D)
3. Square each difference (D2)
4. Find the sum of the squared differences ( D2)
5. Enter ( D2) into the formula where N is the number of couples values
6. Compare the calculated value of Rs with the critical value.
Couple Mean F Mean M Rank F Rank M D D2
M1/F1 7.5 7.2 10 10 0 0
M2/F2 2.1 2 1 1 0 0
M3/F3 4.8 4.3 4 4 0 0
M4/F4 4.7 2.4 3 2 1 1
M5/F5 4 2.7 2 3 1 1

M7/F7 6 4.6 8 6 2 4
M8/F8 5.3 5.8 5 8 3 9
M9/F9 6.3 4.4 9 5 4 16
M10/F10 5.6 5.5 6 7 1 1
D2 36
The formula for the Spearman Rank is:
Rs=
1- 6x36
10(102-1)
=1- 216
990
=0.78 (2.d.p)
Discussion
The results in Tables 1 and 2 show the participants ratings of the photographs. M1 to M10 or F1 to F10 show the photographs, and the letters A to J show the participants score on the photographs. I have then worked out the mean, which is the intermediate between all the values for each photograph it is an average of the results.
In table 3, I have displayed
