Probability sampling consists of three types: random, stratified, and cluster. As stated by (Teddlie et al., 2007), probability sampling is based on underlying theoretical distributions of observations or sampling distributions, the best known of which is the normal curve. Probability sampling is the best strategy for mental health because it allows researchers to create an accurate sample representing the real-life population interest. In supporting my explanation, table 1 in the study shows the means and standard deviations of adolescents’ mental health. This study represents stratified sampling, one of the three probability sampling types.
The table values revealed that there is no difference between males’ and females’ mental health. This study also focuses on numeric data. The relationship between measurement reliability and measurement validity is that reliability can be improved by writing items clearly, making test instructions easily understood and training the raters effectively by making the rules for scoring as explicit as possible (Drost et al., 2011). Validity is concerned with the meaningfulness of research components. When researchers measure behaviors, they are concerned with whether they measure what they intended to measure (Drost et al., 2011).
