Introduction

Introduction:

I am going to do my second piece of coursework in maths called 'Read all about it'. This coursework requires me to gather data from two printed sources. These two printed sources would be a magazine and a newspaper. I will compare the features of a magazine to the features of a newspaper. I am going to try and prove that one has a longer average word length than the other.
I am going to use “IN Baku” magazine and “The Baku Post” newspaper as these are the most readable printed sources in Azerbaijan.

Hypothesis:

My hypothesis is that word lengths in a magazine will be the same on average that word lengths in a newspaper.Further I am going to give one more hypothesis about sentences length in the magazine and the newspaper.

Plan:

1. I am going to buy “IN Baku” magazine and “The Baku Post” newspaper.
2.  I will select 2 articles, 1 from the magazine and 1 from the newspaper.
3. I will be comparing 2 articles on the same topic.
4. In each article I will randomly select 100 words. By selecting one hundred words from each article,

Middle

Mean word length in the newspaper sample was 0,78 letters long.

From these tables I can quite surprisingly see that the magazine and the newspaper have similar amount of word lengths. This is not very easy to see however and because of this I will display this information in a clearer form.

Fig. 1

These charts show me that both articles have similar amount of word
lengths. However I can just about see that the newspaper has longer
amount of word lengths than the magazine. To get the mean,
mode and medium I will create a cumulative frequency table to see
which has the longer word length.

“IN Baku” magazine:

 No of letters per word Frequency Cumulative frequency 1 2 2 2 14 2 + 14 = 16 3 29 16 + 29 = 45 4 14 45 + 14 = 59 5 9 59 + 9 = 68 6 9 68 + 9 = 77 7 7 77 + 7 = 84 8 4 84 + 4 = 88 9 7 88 + 7 = 95 10 4 95 + 4 = 99 11 0 99 + 0 = 99 12 1 99 + 1 = 100 Totals: 100

Now I want to estimate the value of median. I will first draw a cumulative frequency graph.

I will now estimate the value of median by drawing a horizontal line from 50 on the cumulative frequency polygon. Then I will drop a vertical line down to the “No of letters per word” axis and we will be able to read off the value of the median.

After that I will draw the lower quartile (Q1) and the upper quartile (Q3) which I am going to estimate now.

Conclusion

1. I have chosen twenty sentences, whilst it was enough to work on. I would need a much larger sample to give me confidence about whether my hypothesis was true.
1. I have chosen one article from each printed source. It is possible that if I had chosen another article I may have had very different results therefore I should sample more articles.
2.  I have chosen a magazine and a newspaper from one day. If I had more time I would have chosen a number of different reporters, different days and a range of issues.

Overall Conclusion:

Overall I have enjoyed my research. I found it very interesting to
compare two printed sources of which one was a magazine and the other a
newspaper, to see if my hypotheses were correct. Most of my hypotheses
were correct and I was surprised that my analysis on first and second hypotheses was
true, as I have never worked, or ever done any research on amount of words or letters in two printed sources before. In any future research I might see how many sentences were in comparative articles to see if different papers restrict information given to the reader. Also in the future I would like to do a research on many more magazines and many more newspapers, from different days and about different subjects.

This student written piece of work is one of many that can be found in our GCSE Comparing length of words in newspapers section.
