C. Data Analysis

1. The Flesch Reading Ease Formula

In analyzing the data by using the Flesch Reading Ease Formula, the writer uses the following formula: RE = 206.835 – 1.015 X ASL – 84.6 X ASW Furthermore, to find out the number of the Average Sentence Length ASL, the writer divided the number of words by the number of sentences. While, to gain the Average Syllables per Words ASW she divided the number of syllables by the number of words. The following is the calculation of the Average Sentence Length ASL and Average Syllables per Word ASW of the six texts:

1. Text 1 entitled: John’s English Teacher; 19 sentences, 290 words, and

429 syllables ASL = Number of words : Number of sentences ASL = 290 : 19 = 15.26 ASW = Number of syllables : Number of Words ASW = 429 : 290 = 1.48

2. Text 2 entitled: Lions; 26 sentences, 300 words and 409 syllables

ASL = Number of words : Number of sentences ASL = 300 : 26 = 11.54 ASW = Number of syllables : Number of Words ASW = 409 : 300 = 1.36

3. Text 3 entitled: Life in Ancient Rome; 24 sentences, 372 words and

586 syllables ASL = Number of words : Number of sentences ASL = 372 : 24 = 15.5 ASW = Number of syllables : Number of Words ASW = 586 : 372 = 1.57

4. Text 4 entitled: Steve’s Favorite Sport; 20 sentences, 256 words and

354 syllables ASL = Number of words : Number of sentences ASL = 256 : 20 = 12.8 ASW = Number of syllables : Number of Words ASW = 354 : 256 = 1.38

5. Text 5 entitled: Rossi Sweeps to Australian GP Victory; 14 sentences,

408 words and 678 syllables ASL = Number of words : Number of sentences ASL = 408 : 14 = 29.14 ASW = Number of syllables : Number of Words ASW = 678 : 408 = 1.66

6. Text 6 entitled: An Unforgettable Experience; 28 sentences, 311
