LESSON 24 - SPLIT-HALF RELIABILITY: DETERMING SPLIT-HALF RELIABILITY USING SPSS

In lesson 23, we have defined reliability as the measure of stability of a test. We have also said that there are two main methods of determining reliability. This is repeated measurements and Internal Consistency method. Under repeated measurements, we have three main reliability tests: Test-retest, Alternative forms and equivalent forms.

Lesson 24 will discuss internal consistency methods of determining reliability. Internal consistency method of determining reliability indicates the degree of homogeneity among items in an instrument. It is estimated by determining the degree to which each item in a measure/instrument correlates with each other item in the same measure/instrument.
Internal consistency is based on a single administration of a measure.
There are two types of Internal Consistency reliability:
a) Split-Half and
b) Alpha Coefficient methods

In this lesson, we shall discuss Split-half. This is where a measure is split into two before analysis to create two sets of tests. Each section is scored separately from the other section. Then a correlation coefficient is determined by correlating the two sets of scores.

This lesson will also demonstrate how to use SPSS to determine split-half. SPSS (Statistical Package for Social Science) is a software that analyses quantitative data.

Make sure you go through lesson 23 before lesson 24 so that there is coherence in your learning.

Am learning methodology in Italian and am a beginner in Italian language. Thanks for this class, am hoping to learn here….

[theresaosusu]

An excellent job please will like to know u better

[florencearagbaakpore]

thanks for the class but the scores are not clear are they over 100 or above 100

[aseweelizabeth]

Clear but create more time for the demonstration part.

I have listened to the last part demonstration of spilit half using SPSS honestly im not getting it.
