Objective
Analysis of a language text, using graphical and pie chart techniques.
DESCRIPTION : -
1) I selected a paragraph containing approximately 250 words from any source example newspaper etc. 2) I read every word and obtained a frequency table for each letter of the alphabet ( table 1). 3) I noted down the no. of two letter words, 3 letter words and so on and obtained a frequency table (table 2). 4) I selected 10 different words from the text which had frequency greater than 1. Gave ranks 1, 2, 3 ----------- 10 in decreasing order of their frequency and obtain table 3. iC

The Paragraph
EROSION OF ESSENTIAL VALUES AND THE NEED OF OVERHAULING EDUCATION SYSTEM
Education is a sub-system of the wider social system. Although it functions autonomously, it has linkage with the economic, political, religious and other sub-systems which enter a powerful influence on the goals of the educational sub-systems. Due to globalization and modernization, our society is passing through momentous changes in its value system. Values of yesteryears have taken a back seat and materialism, corruption and dishonesty and other negative values have come to the foe. At this junction, all formal and in-formal agencies of education like family, school and community should realize the explosiveness of the situation. It is rightly said values can not be taught, they are caught.

All the agencies should become role models if we want our youth to be on the right path. Absence of a congenial and loving atmosphere and quarrel among parents are the major hurdles in this direction. Race for degrees and jobs has deteriorated situation. On the other hand, formal education is squeezed between memory and mechanisation. The whole system of education needs complete overhauling. If at all we the citizens are desirous of thwarting deterioration in values, teaching at all levels must emphasize a marvel education and character building. Intellect without wisdom can be suicidal.

Pie chart - 1
Angle of vowel A = ଵଷଷଵଵ଼ସ x 360 = 38°
Angle of vowel E = ଵସଵଵଵ଼ସ x 360 = 42°
Angle of vowel I = ଵହଵଵ଼ସ x 360 = 33°
Angle of vowel O = ଽ଼ଵଵ଼ସ x 360 = 30°
Angle of vowel U = ହଵଵ଼ସ x 360 = 17°
Angle of consonants = ଽଷଵଵ଼ସ x 360 = 200°

From table 2 (a) Compared the frequency of two letter words, three letter words and so on. (b) Made a pie chart(2) and made a interesting patterns. Ans:- (a) 2 letter � 40, 3 letter � 51, 4 letter � 17, 5 letter � 20, 6 letter � 32, 7 letter � 22, 8 letter � 20, 9 letter � 20, 10 letter � 3, 11 letter � 6, 12 letter � 4, 13 letter words � 6

From table � 3 (a) The relation between the frequency of a word to its rank. Ans: (a) Higher the rank of a word, higher is its frequency. (b) Plot a graph between the frequency and reciprocal of word rank. What do you observe. Do you see any interesting patterns?
Graph CONCLUSION The project given to us which was based on frequency has done a lot good to us. This has also helped us to learn how to find the frequency of letters from given text and also to plot their graph and pie chart.
