the extent to which a test measures a representative sample of the subject matter or behavior under investigation. For example, if a test is designed to survey arithmetic skills at a third-grade level, content validity indicates
how well it represents the range of arithmetic operations possible at that level
.
How do you use content validity?
The formula of content validity ratio is
CVR=(N
e
– N/2)/(N/2)
, in which the N
e
is the number of panelists indicating “essential” and N is the total number of panelists. The numeric value of content validity ratio is determined by Lawshe Table.

the selection procedure, and explain why certain parts of the domain were or were not …

if it covers all topics taught in a standard 9th-grade biology course
.
What does it mean to say content validity?

how well a test measures the behavior for which it is intended
. If the test does indeed measure this, then it is said to have content validity — it measures what it is supposed to measure. …
What is the purpose of content validity?
Content validity

What is the importance of content validity?

extent to which the set of items comprehensively covers the different components of health to be measured

The K value should be above 0.74 to be considered excellent;
between 0.60 and 0.74 is good
, between 0.40 and 0.59 is fair and below 0.40 is poor (Cicchetti and Sparrow, 1981). Generally, researchers recommend that a scale with excellent content validity should have I-CVIs above 0.78 (Shi, Mo et al., 2012) .
How do you determine validity?
Validity refers to
how accurately a method measures what it is intended to measure
. If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world. High reliability is one indicator that a measurement is valid.
