Question : Hi,
I'm using an ANCOVA to compare metabolic rates of some birds populations, using mass as a covariate. I understand that it would be more appropriate to report estimated marginal means (or least square means, as other statistical packages call it) because they take the covariate into account. However, I don't know how to produce bar graphs using EMMs. I'm using SigmaPlot to make my graphs, and I can make vertical bar graphs just fine having it calculate the mean +/- SE, but how do I get it ..
Answer : What version do you have, and does it include beta features?
Question : Here are data on the percent of females among people earning doctorates in 1994 in several fields of study.
Computer science- 15.4%
Life Sciences- 40.7%
Physical Sciences- 21.7%
Would it be correct to use a pie chart to display these data? If so, construct the pie chart. If not, explain why not. You dont need to construct the pie graph if you say a pie graph will work.
Answer : Briefly, No a pie chart will not work.
This has 6 different populations. A pie graph works with 1 population adding to 100%. Since these are from separate populations, a bar graph would be suited for displaying this data. You could do a comparison of male to female in each of the fields of study.
Question : I need an article with bar graph. for a project. Not an article on bar graphs.
