Maths Coursework - URGENT PLEEEAAWatch
when analysing the articles I would only deal with verbs and adjectives... some nouns, perhaps, but as Helen said don't bother with names of any kind. also you should look at articles about similar topics... or at least similar lengths. make this last point clear in your coursework as it would be a huge flaw if you were comparing articles of significantly different sizes.
you will eventually want to calculate averages for the 3 different newspapers/magazines. before doing this, however, there should be some analysis. your conclusion will be geared towards proving the thesis, but you should at least point out any magazine articles that have longer word lengths than a newspaper article (there's bound to be one).
when you have the averages you should put the data in a culmulative frequency graph. this will show the range, median, upper and lower quartiles of both the average word length in a magazine article and the average word length in a newspaper article. it's also an idea to accompany any graphs you do with a box-and-whiskers diagram, to show the results a little clearer.
something I haven't mentioned is s.d. whenever you are analysing some results in your thesis you have nothing to lose by calculating the s.d.
