    Unhappy Please help a very confused Paramedic Student




    As part of my final year Bsc degree I am writing a research proposal.
    HOWEVER I am struggling to wrap my head round which statistical test would best suit my data.

    The Research is an RCT with an intervention and a control group (2 groups). I would like to compare the incidence rate of Post-partum haemorrhage (PPH) between the two groups. PPH either occurs or does no occur, is this binary data? ??
    I understand this to be a Parallel Group Study

    My Null hypothesis is that the intervention will not reduce the incidence rate of PPH when compared to the control group

    Alternate hypothesis is that the intervention will reduce the incidence rate of PPH when compared to the control group

    How would i go about this? My current thinking is a Two Sample t Test with unequal variances and to use Intention-to-treat analysis also.

    Thank You to anyone who can help me

    Your outcome is PPH yes / no, so your outcome would not be best addressed with a ttest. I would recommend a Fisher's exact test.
