Why is variation in a candidate measure within population important to assessing the measure validity?

Expert Solution

solution :

variation :

Proportions of variety are utilized to portray the conveyance of the information. The range is the contrast between the best and slightest information esteems. Quartiles are values that gap the informational collection into four equivalent amounts of.

measure validity :

Legitimacy of an evaluation is how much it gauges what it guessed measure. This isn't the equivalent as dependability, which is the degree to which an estimation gives results that are exceptionally reliable.

importance of variation in assesing the measure validity :

In order for assessments to be sound, they must be free of bias and distortion. Reliability and validity are two concepts that are important for defining and measuring bias and distortion.

1. Prescient legitimacy proof

2. Simultaneous Cirterion-related legitimacy

3. Content Validity

.
4. Build Validity proof

5. Test-retest Reliability

6. Exchange Form Reliability Equivalent

7. Inward Consistency

Genetic variation is the difference in DNA sequences between individuals within a population. The human genome has about 3 × 109 base pairs of DNA, and between any two humans, the amount of genetic variation is about 0.1%. In other words, about 1 bp in every 1,000 bp of DNA will be different between two random individuals. Any two individuals have about 6 × 106 base pairs that are different. Therefore, we can say that there is considerable genetic variation...
