personal investigation 2

• what is the operationalised hypothesis?

  there will be a positive correlation between the time taken (secs) on the stroop test and creativity scores. As time taken to do stroop test increases, so will the creativity scores
• what is the operationalised null hypothesis

  there will be no correlation between the time taken to do the stroop test and creativity scores
• is the hypothesis directional or non-directional

  directional as there has been previous research
• why did you operationalise these co-variables in this way?

  to make them clearer
• what are the operationalised variables

  creativity scores on the Kellogg creativity questionnaire out of 116

  time taken to do the stroop test in seconds
• what confounding variables did you have

  colour blind

  dyslexia

  sleep
• how did you deal with the confounding variables

  asked them if they were colourblind before starting
• what extraneous variables did you have

  temperature

  time of day

  noise

  light levels
• how did you deal with the extraneous variables

  made sure they were in a quiet place where it was easy to see the computer screen
• define a correlation

  a relationship between two co-variables
• what are strengths of a correlation

  can be simplistic

  can identify trends
• what are weaknesses of a correltion

  cant establish cause and effect

  low internal validity
• what sampling frame did you use

  opportunity sampling
• why did you use this sampling frame

  its much easier to gather research in comparison to other methods, for example, stratified which may be more costly in time and resources
• what is opportunity sampling

  when you use people who are available at the time
• how will you ensure internal reliability is high

  standardised procedures- same measures
• could you check for external reliability?

  not repeated=no external reliability
• what specific validity issue may affect your research

  social desirability- may want to get the same scores as peers
• which graphical representation did you use

  scatter graph because we have correlation
• which inferential statistic did you use

  spearmans ratio
• why did you use this inferential statistic

  its ratio level

  correlation

  dont use questions
• were the results significant

  the observed value -0.35758 is less than the critical value 0.45 so the results are non significant
• what conclusions can be drawn from your findings?

  there is a weak negative correlation between stroop test performace and creativity
• what are 2 ways which your research could be improved?

  increase sample by having more participants

  complete a test-re-test to check the reliablity
