    I wouldn't call it simplicity, because what if on day 5 I have 1000 survivors? Do I need to enter zero 1000 times? There must be other option. For example I have already % of survivors at certain hours post infection and I don't see the point in changing it back to numbers of survivors.

    I agree with Constantine because at day 5 group A loss animal not at day 4

    In day 5 we lost a subject in group A not in day "4"

    I'm pretty sure there's an error here. Group A loses an animal on day 5, not on day 4...

      this is a survival graph. It tells you how many animals survive at a particular point of time, not how many died. This graph shows that in group A at day 5, 4 animals survive. clear?

      You are right.

      @@debasishroy1351 Yeah, but he calculated differently on the other group.
      Ha said one death happened in day 5 on Group A and added 4 - 1.
      Than in Group B death happened on the 2nd day and he added 2-1.
      So either this or that solution but there's definitely an error in it, which on is the wrong is the question....

    As far as analysis goes, is there a way to find the confidence interval and hazard ratio? Or does prism use 95% CI?

  • @BigBoss-gb4cx
    @BigBoss-gb4cx 5 ปีที่แล้ว +2

    For the Group A" shouldn't it be 5 - 1 instead of 4 - 1, since the death happened on the last (5th) day?

    I'm sorry but this is so confusing. I almost would rather do the calculations myself by hand. Lol

    Hi great video- was wondering do you do ny personal tutoring? also was wondering how would you code the data for larger numbers, eg my experiment involves survival rate of celegans exposed to a restricted diet!!! however my basal rate starts at 330, so subsequent weeks involve large deaths, how would I plot this in prism please x

    How you enter the data if you lose more than one patient a day?

    • @DoryVideo
      @DoryVideo  4 ปีที่แล้ว

      Just put in the day twice with a 1 in each line

    hi! what if my data is in percentage? can I input the data in the form of percentage in different time points? I am looking at the survival of cells not patients.. thank you

    • @DoryVideo
      @DoryVideo  9 ปีที่แล้ว

      Good question. I've not ever needed to enter data in that way. If you have data as a % you may have problems with the plotting of the data as that is not the way Prism is designed to handle the data. I'll check and get back to you.

    It is much better to do standard (normal) graph. Much easier and faster than this struggling.
