    thanks Dr Whitney, i was confused about experimental research design but though your explanations now am clearly understanding the concept.

    Ashley Bryant GOL 106 V1. I learned that scientific research must be studied using a control group, a baseline, to compare against a study group, a group that has exactly on variable that is different than the circumstances of the control group and is then compared against the control group to accurately determine what the effect of the given variable is.

    For some research, it's beneficial to have multiple characteristics that differ the experimental group from the control group. In my area of research, we're currently exploring the effect gene mutations have on the efficiency of protein activity. Because of the nature of epigenetics and how various genetic loci can regulate gene expression, it's essential to test how various combinations of multiple amino acid mutations affect protein translation and activity. And then comparing the different mutation combinations against one another to identify possible links between genetic loci based on observing a significant difference in protein activity. In this case, the control serves as a way to verify that the proteins were naturally translated and could function at a standard degree of efficiency in the particular cellular environment of the study.

    Question. "The controlled variables don't affect result." I thought the result is den dependent variable? If yes, then the controlled variables have an affect on the result?

    • @Jimmyligma
      @Jimmyligma 4 роки тому

      The controlled variables are not ment to affect the result. They keep the experimental environment and surroundings the exact same to increase accuracy.

    Hi I m a new research scholar..I have decided to conduct an experiment with 1 control group n 2 treatment groups..Shall I take a total of 30 samples for all the 3 groups together?

    • @BiologyProfessor
      @BiologyProfessor  2 роки тому

      To determine adequate sample size, you can do a test called a power analysis. A statistician can help with this. Otherwise, you are guessing. 30 samples total (10 per group) may be acceptable, but it’s definitely on the low end and may not be a large enough sample size. If you can reasonably do 20 or 30 per group, that’s probably better. But it’s hard to know without more information and a power analysis.
