Are IQ scores discrete or continious?
IQ scores are typically considered discrete because they are reported as whole numbers, often ranging from around 40 to 160 in standard testing. While the underlying intelligence being measured can be seen as a continuous trait, the scoring system used in IQ tests categorizes this trait into distinct values. Therefore, while the concept of intelligence may vary continuously, the presentation of IQ scores is inherently discrete.
