results. There are many different levels of measurement. All levels have different ways numbers can be used. One level is the nominal level. At this level Numbers can be used for tags or labels like Barcodes and social security numbers. When using nominal variables measurement means is classified as classifying cases in groups. These groups “must cover all cases” and can not belong to several groups ("Levels of measurement‚”). Ordinal Level is another level of measure. With this kind of measure
