![]() ![]() create a new data table File -> New -> New data table and graph. ![]() The other six columns contains values for red blood counts from 3 wild-type fish and 3 mutant fish. The first column contains X-values: days after infection. What type of table are you going to use ? How many biological replicates were measured?Īs you can see we measured 3 fish from each group on each time point. Open the file in a text editor to see that semicolons are used as a column separator. What is used as a column separator in this data set? In that case, you would have to use a mixed or a multilevel model.ĭownload the data set of this exercise. If this was the case the data would be dependent and linear regression would not be the appropriate technique to analyze the data. Note that it is important that I do not use the same fish for all the measurements. I want to see if the mutant fish respond differently as the wild-type fish. Every 2 days, I take 3 fish from each tank and measure their red blood count. ![]() To this end I have infected a tank of mutant zebrafish that do not respond to interferon and a tank of wild-type zebrafish with the pathogen. I have done an experiment to assess the effect of interferon on anemia during pathogen infection. ![]()
