bar chart) of women/men. Let's have a look at an example of how to present the same data in different ways to prove opposing arguments. You have more confidence in results that are based on more cells, or more replicates within an animal, so just taking the mean for each animal by itself (whether first done on replicates within animals or not) wouldn't represent your data well. A continuous outcome would also be more appropriate for the type of "nested t-test" that you can do with Prism. height, weight, speed, time, revenue, etc.). A percentage is also a way to describe the relationship between two numbers. I will probably go for the logarythmic version with raw numbers then. The higher the confidence level, the larger the sample size. I think subtracted 818(sample men)-59(men who had clients) which equals 759 who did not have clients. We have later done a second experiment in very similar ways except that we were able to sample ~50-70 cells at one time, with 3-4 replicates for each animal. I also have a gut feeling that the differences in the population size should still be accounted in some way. Before implementing a new marketing promotion for a product stocked in a supermarket, you would like to ensure that the promotion results in a significant increase in the number of customers who buy the product. All Rights Reserved. The second gets the sums of squares confounded between it and subsequent effects, but not confounded with the first effect, etc. number of women expressed as a percent of total population. The weight doesn't change this. For example, is the proportion of women that like your product different than the proportion of men? To answer the question "what is percentage difference?" That's a good question. Would you ever say "eat pig" instead of "eat pork"? How do I account for the fact that the groups are vastly different in size? I am working on a whole population, not samples, so I would tend to say no. 1. I have several populations (of people, actually) which vary in size (from 5 to 6000). Acoustic plug-in not working at home but works at Guitar Center. Regardless of that, I don't see that you have addressed my query about what defines precisely two samples in this set-up. Can I connect multiple USB 2.0 females to a MEAN WELL 5V 10A power supply? You need to take into account both the different numbers of cells from each animal and the likely correlations of responses among replicates/cells taken from each animal.
