In order for a measuring instrument to be considered appropriate for a research, it must be an accurate indicator of what is intended to be measured, easy to use and efficient. To evaluate a measurement tool, three main criteria are required: validity, reliability and practicality. Validity refers to the degree to which a test measures what it actually wants to measure; the reliability is related to the acuity and precision of the measurement procedure and the practicality is related to factors of economy, convenience and interpretation.
