Introduction

Suresh is comparing magazines and newspapers. He chooses a passage from one newspaper and one from a magazine. They each contain 100 words and he counts the length of all the words.  Suresh then says that the magazine has the shortest words.

Write a hypothesis about the length of words in newspapers and magazines.

Design and carry out an investigation to test your hypothesis.

Aim

My aim is to establish whether the words in a magazine are actually shorter than the words in a newspaper by comparing and contrasting the two; by applying as many statistical comparatives as possible.

Hypothesis

My hypothesis is that the words in both newspapers and magazines depend on the readers, target market, that the article is pitched at and the amount of sophisticated language within the text. Comparatives include tabloids and broad street publications. However I think that magazines in general

Conclusion:

I have noticed that both the newspaper and magazine have similar results. The length of words are more commonly grouped between 3-7 letters, however not in line with the mean.  Magazines have a lower mode and more frequency in lower letter word. It was a strong probability that magazines would have shorter words, therefore, Suresh’s hypothesis and min own stand correct on the basis of this experiment.  Magazines have shorter words than newspapers.
