A pre-requirement to conducting data analysis in Excel and SPSS is to understand the level of measurement. Provide an evaluative research example to illustrate that you are knowledgeable about the levels of measurement of variables that are generally used in evaluative research in human services?

Question

What will be an ideal response?

Answer 1

Ans: A specific example such as a study on the effectiveness of alternative therapies such as the recovery model-based therapies on problems such as anxiety, phobia, or depression with the identifications of at least four variables with one of the four each to describe each level of measurement. Nominal level measurement must be described with either a mutually exclusive or a categorized variable such as gender, religious affiliation, political party affiliation, or ethnic background of the participants in the recovery model-based alternative therapies. Ordinal level measurement must be described with examples such as birth order of the participants in the therapeutic modality, arranged in an ascending or descending order. Interval level measurement must be described with examples such as scores on the scales for anxiety or depression with at least some understanding of the emphasis on this being necessary to compare means and calculate descriptive central tendencies such as means and variations such as standard deviations. Ratio level measurement must be described with a true zero point, with examples such as the distance travelled by the participants to the treatment center.
