A Establishing the Repeatability and Reliability Integrity of the Mathematics Value Scale (MaVscale)

Abstract

The mathematics value scale (MaVscale) is a 27-item scale that has been developed for measuring the mathematics value in the learners. In the development of a scale, one of the aspects of scale development is the repeatability and or reproducibility aspect. This aspect of the scale development is germane, for the effective usage of the scale. So, this study was done to establish the repeatability integrity of the MaVscale. Descriptive survey research type was adopted for collection of data, while descriptive statistics and reliability statistics in SPSS were adopted to analysed the data. The results of the data analyses showed that 11 items have 0.00 variation, 10 items have 0.01, 3 have 0.02 and 1 has 0.03. The reliability coefficients (r) of the first repeatability = 0.96, while the reliability coefficients (r) of the first repeatability = 0.91. These imply that the repeatability variation is very small, making the repeatability to be very high as the MaVscale consistently measures the construct of interest, Mathematics value.
