    Which statistical test to use for my data analysis




    Hi everyone,

    Could someone help me to know which statistics should i use for my data analysis.

    I did my project on "personal exposure to PM2.5 among different villages". Sample size is 400 from 30 different villages. Among these 400, 40 subjects have 6 time PM measurement and the rest 360 subjects have 2 time PM measurement. The sample size among each village is different. I am curious to know which statistical test should be used to report the personal PM2.5 exposure among different villages. I also want to report variation of personal PM2.5 exposure among the 40 individuals with 6 time measurement based on month wise and season wise (pre and post monsoon). Thank you.

    Hi, welcome. Are you sure you want to do a test? What is the hypothesis you will be testing?

    I would just report descriptive statistics, e.g., means with confidence intervals and standard deviations.

    Hi Junes

    My null hypothesis is age/gender will not influence the exposure to PM concentration.

    So you are more interested in the correlation of age and gender with PM concentration, and the villages are more of an annoying source of variation?

    In that case I would look into multilevel/mixed models.
