Biological practical Flashcards
What is the aim of the biological practical?
Aim: To conduct a correlation to the relationship between testosterone (shown by 2D:4D ratio) and aggression
(shown via aggression questionnaire)
Which research method did we use to collect our results?
Correlation
What is the alternative hypothesis for your biological practical?
There will be a positive relationship between 2D:4D ratio, and score on an aggression
questionnaire.
What is the null hypothesis for your biological practical?
There will be no relationship between 2D:4D ratio and score on an aggression questionnaire.
What are your two co-variables in the biological practical?
2D:4D ratio and scores on an aggression questionnaire / 15
What type of sampling did you use in your biological practical?
Opportunity sampling
What was the sample of your biological practical?
______ people from college in the North of England, aged between 16 and 20
What questionnaire did your sample complete in the biological practical?
30 questions about their aggressiveness and measured
on a 5 point scale giving them a total for aggression
How did you measure the participants level of testosterone exposure in the biological practical?
measuring the length of their ring finger and index finger and measuring the
ratio between the two
(2D:4D ratio)
What graph could you use to plot the results of the biological practical?
Scatter graph
Why was the sample of your biological practical neither androcentric or gynocentric?
both males and females in the finger ratio measures/aggression questionnaire making it more
generalisable. This means the results would be more representative about the correlation between finger ratio and
aggression in a wider population
How was your biological practical reliable?
The questionnaires about aggression and the finger measures are standardised which means it can be easily
repeated. This is good because the procedure can be repeated to see if the results about the correlation with finger
ratio and aggression would be the same.
What is the strength of you collecting quantitative data in your biological practical in terms of mean aggression scores /15 and 2D:4D ratio?
A strength is it used quantitative data from the aggression quesitonnaires which allows for statistical
testing/analysis. This is good because we can to see if the results about aggression and finger ratio are due to chance
How is your biological practical ethical?
The study is ethical as participants knew we were measuring their aggression levels and their finger ratio as a
proxy for testosterone when they consented. This means we have consent for the research as participants were fully
aware of the purpose and that we would discuss their aggression
How is your sample NOT representative in your biological practical?
Why is this a problem?
This has small opportunity sample from the same sixth form college in the north east completing the aggression
questionnaire so not generalisable because they might share characteristics. This is a problem because the results
about the relationship between aggression and finger ratio might not be applicable to non-teenagers.
