Dear all,

Wish you all a healthy 2012. I appreciate your comments for the appropriate analyses for the following data set.

270 written scripts by test takers across three L1 backgrounds: A, B, & C are rated by trained and experienced raters at levels of 5, 6 & 7 as presented in the followig table.

	L1
Level	A	B	C
5	30	30	30
6	30	30	30
7	30	30	30

To check the validity of the ratings we've analysed the scripts using some textual features such as Word Frequency, Syntactic complexity, and Cohesion. We now want to find out:

1) Is there a sig. difference between the scripts belonging to levels 5, 6, & 7 in terms of any of the three text features (WF, SC, and Cohesion)?

2) Is there a sig. difference between the scripts at the same level (5, e.g.) across the three L1s (A, B, & C) in terms of the three text features?

3) Is there a sig. difference between the scripts at the three levels (5, 6, 7) for each L1 (A, B, & C)?

 

Any suggetions for appropriate statistical anslyses to answer these RQs is much appreciated.

Regards;
Mehdi
