F. Research Hypothesis
Hypothesis test is used to determine the influence of pre-questioning model on the reading comprehension achievement. Hypothesis test in this study
use the formula t test. The steps in testing this hypothesis is as follows:

c. Determine the test criteria
To determine the criteria for testing on data processing operations carried out by calculation, testing to see a comparison between t
count
with t
table.
d. Perform deduction

CHAPTER IV FINDINGS AND DISCUSSIONS
In this chapter, the writer would like to present the description of Results of Pre-test in Experimental Class and Control Class of Analysis of the Data,
Results of Post-test in Experimental Class and Control Class of Analysis of the Data, Recapitulation, and Data Analysis of Testing Requirement.
A. Findings
This part will discuss about the results of pre-test and post-test in experimental class and control class analysis of the data.
1. Results of Pre-test in Experimental Class and Class Control Analysis of
the Data
The following is the score of experimental class and control class in pre-test.
