Level 5 Research Methods – Case Study on Quantitative Data Analysis – Individual Project
Go to the NZ Census at School Website (https://new.censusatschool.org.nz/tools/random-sampler/) and download a 200 person sample of UK students (Random Sampler) from the CAS International database. Each of these will be a random sample so no two samples will have the same data so copying another person’s work will be obvious!!!!
You should complete the tasks below – please read them CAREFULLY (especially the HINTS) and only do what is required – anything extra will be good practice but will not get you any more marks!!!

Task Output Required for Assessment Marks Assigned For each of the research questions below, generate an appropriate graphic with an associated paragraph explaining your findings. HINT graphs should be different types for each part What is the age distribution of your sample, and does it differ between the genders? Image in Word File with brief text description 10 Is there a relationship between Height and Arm-Span and does this differ between genders? Image in Word File with brief text description 10 How does the Median and Range of Heights vary with age and does this differ between genders? Image in Word File with text description 20
Statistical Analysis

HINT there should be different tests for each section Is there a statistical difference in reaction time between genders in your sample?
Is there a statistical difference in the scores for saving energy and the importance of owning a computer in your sample?
Word file with details of the test used, justification of the test (based on YOUR data and findings) and appropriately formatted results of your chosen statistical test 20.
