If any of the conditions are not met, the measure will not be accepted for consideration. Several conditions must be met before proposed measures may be considered and evaluated for suitability as voluntary consensus standards. We most commonly encounter integers when we count things, but they also often occur in psychological measurement.The criteria include the approved recommendations from the 2012 projects on patient-reported outcomes, composites, and eMeasure feasibility. Integers are whole numbers with no fractional or decimal part. The number 1 is equal to the logical value TRUE, and the number zero is equal to the logical value FALSE. In fact, most programming languages treat truth values and binary numbers equivalently. This can be especially useful when we start using programming languages like R to analyze our data, since these languages already understand the concepts of TRUE and FALSE. It’s often useful to instead use logical values, which take the value of either TRUE or FALSE. For example, I might ask 10 people if they have ever experienced a migraine headache, recording their answers as “Yes” or “No”. We will often use binary numbers to represent whether something is true or false, or present or absent. The simplest are binary numbers – that is, zero or one. It’s important to understand these differences, in part because statistical analysis languages (such as R) often distinguish between them.īinary numbers. There are several different types of numbers that we work with in statistics.
