    Thank you so much, I was finding this section so overwhelming, but this really helped make everything more clear

    Hi, I'm still confused how to collect database which I mean statistical data , plus my research question is "How does the change in temperature (70°C, 75 °C, 80 °C, 85 °C, 90 °C) affect the rate of the decomposition of ammonium carbonate? "
    For example, does the quantitative data has to be copy paste from a resource or what?

    Hi, I did my IA on the effect of pH on plant growth, but I'm unsure how to formulate my hypothesis and which stats test to use. How would you formulate a hypothesis for a pH experiment?

      Edna, not knowing completely your question and experimental design, my general recommendation would be to ensure you have a wide range (at least five) pH values tested and a minimum of five trials for each. This would enable you to create an XY scatter graph and correlation test for your analysis. Good luck.

    Hi, I was wondering that app/program I should use to make my graph. Would excel suffice or do I have to pay for other programs like Logger Pro? Thanks.

      I would recommend using Excel or Google Sheets. Logger pro is to be used with Vernier probes and really is just used to collect data, not analyze the data. If you have access to a probe, I highly recommend using them for your IA data collection: digital data collection is always best.

    do i need uncertainity if i have a database IA?

      Only if the database provides it. If it does not, be sure to address that they were not provided
