Statistics Project Essay Example For Students

Statistics Project Essay My task during this statistics coursework is to gather relevant information regarding the memories of people with regard to many different factors. I shall need to create numerous hypotheses that are sensible and are practical to carry out, get information relevant to the hypotheses and present the data in different methods which are relevant to the experiment. Hypothesis My primary hypothesis is that pictures are easier to memorise than words, and words are easier to memorise rather than numbers. I have come to this prediction as I personally find pictures easier to remember because you can relate it to something and it is visual, visual objects are said to be easier to memorise. Secondly words are easier to memorise than numbers because words can be easily related to ones thinking and therefore people can remember them easily while numbers are harder to relate. : I decided to choose similar pages from both the Times and the Mirror with roughly equal numbers of paragraphs and adverts, pages 4-5, or 4-6, as in the Mirror there were not enough to take samples from. To find mean sentence lengths in the two papers, I decided I would sample systematically from my populations, counting the number of words in every 3rd sentence. I came up on several problems quickly should I include headlines in my count? I decided against it, as headlines tend to be shorter than normal sentences. The next problem came with numbers did they get counted as words in the sentences? Making sure that I did the same with both papers, I decided to exclude numbers in my count. I also decided to exclude any sentences in adverts, as the number of adverts on the compared pages varied. I then took a mean and found the of my data. To find the average number of words per sentence, I decided to cluster-sample, and count the first 30 words in the first paragraph of page 4 in each paper. I decided that I would again exclude numbers, and that hyphenated words counted as a single word. Again, when I found all the data, I found its mean and the standard deviation. Location: As can be seen from this box and whisker diagram, the Times has a similar mean sentence length (20 to 1sf.) to the Mirror (18). This shows that the average sentences in the Mirror and the Times contain a similar number of words. In the box and whisker diagram for word lengths, it is visible that their medians are the same.
