You make a series of statements. Some of them you make true and some of them you make false. It's up to you to decide how many of each you want to put into your test. You shouldn't make them too obvious or everyone will get 100%, but don't make them so tricky that everyone fails either.
It's simple construct an experiment!
A validation study addresses the questions of what a test measured (construct validity) and how well it measured it (criterion validity and reliability). Construct validity examines if the test measures the intended construct or trait. Criterion validity examines if the test results predict or correlate well with other measures. Reliability examines the consistency and stability of the test scores over time.
To ensure the validity of a test, it is essential to clearly define the construct being measured and to align test items with this construct. Conducting a pilot test can help identify any ambiguities or biases in the questions. Additionally, using established validation methods, such as content, criterion-related, and construct validity assessments, will strengthen the test's credibility. Regularly reviewing and updating the test based on feedback and new research also contributes to maintaining its validity.

When a test actually measures what it is supposed to measure, it has validity. Validity ensures that the test accurately reflects the concept or construct it is designed to assess, whether that be knowledge, skills, or other attributes. Different types of validity, such as content validity, criterion-related validity, and construct validity, help establish the overall effectiveness of the test in measuring the intended outcome.
The differences in test scores, or predictions from those scores, between two or more subgroups of the population that are matched on the underlying construct being measured.
This is known as the validity of a test. It is the degree to which a test accurately measures what it claims to measure. High validity indicates that the test is accurately assessing the intended construct or concept.
The validity of a test refers to the extent to which it measures what it intends to measure. It assesses if a test is actually capturing the construct or concept it is designed to measure. Validity is essential to ensure that test scores are meaningful and can be generalized to the intended population.

they are many tests to be conducted when we are going to construct a new road such as: - sieve analysis - hydrometer tests(not necessary) -compaction test - CBR test -sand cone test - abrasivity losangeles test - Standard penetration test - standard proctor test
To determine if a test measures what it is supposed to measure, one must evaluate its validity. This involves examining whether the test effectively assesses the intended construct, such as through content validity, criterion-related validity, and construct validity. Additionally, analyzing test results and comparing them with established benchmarks or outcomes can provide insights into its effectiveness. If the test consistently correlates with relevant criteria and accurately reflects the targeted concept, it can be considered valid.
