Assignment

Tittle: The Correlation between Students’ Interest in Reading English Text, Students’ Self-Esteem and Reading Skill at the Eleventh Grade Students of SMKN 1 Sragen in the Academic Year of 2017/2018

- Validity of the instrument

Ary et all (2010:225), validity is the most important consideration in developing and evaluating measuring instruments. He also states that validity is defined as the extent to which an instrument measures what it claimed to measure. There are two kind of validity; internal and external validity. In this study, the researcher uses internal validity since the researcher analyzes the items of instruments whether or not they are appropriate to use. To measure the validity of reading interest, self-esteem and reading skill test, the researcher used Product Moment Formula. There are three data of validity instrument, namely; reading interest, self-esteem and reading skill. After being computed the data try out of three instruments of students that consist of 32 students

- Reliability of the Instrument

Arikunto (2006:178) says that reliability refers to the understanding that a sufficiently reliable instrument to be used as a means of collecting data because the instrument is good. Sugiyono (2010:173) states that reliability is an instrument when used several time to measure the same object, the result of data will consistency or stability.  To measure the reliability of reading interest and self-esteem questionnaire and the reliability of the reading skill test, the researcher used the Split-Half Spearman Brown Value to compute the reliability test.

- The Validity of the Instrument

The validity was probably the single most important aspect of the design of any measurement instrument in education research. Validity was defined as the extent to which an instrument measured what it claimed to measure (Ary et.al, 2010: 225). Arikunto (2013: 211) states that validity is a measure that indicates the levels of validity or validity the instrument. The validity of an item could be shown by doing item analysis. It was counted using Product Moment formula.

- The Reliability of the Instrument

Reliability test refers to degree to which a test is consistent and stable in measuring what it is intended to measure (Sugiyono, 2006: 174). Reliability refers to the stability or the consistency of the test, if the instruments is used many times to measure the same objects would be give the same result. Beside having high validity, a good test should have high reliability also. Reliability refers to the extend to which test scores are free of measurement error (Muijs, 2004: 71).  In this research, the researcher used Belah Dua method to measure the question. This method was chosen because the point that used only one device. Belah Dua method is a method of reliability testing that is done by dividing the side problems into two parts, next correlating the total score of both. The way of splitting the side in this research was using butir awal and butir akhir (Purwanto, 2009:160). Spearman-Brown formula was used to count the reliability of the instrument.
