validity is whether the results are valid so the data has no mistakes of as such in it whereas reliability is the dependability; when the results you have are accurate and are of enough quality.
* Probability * Correlation * Validity * Reliability * Variable * Frequency distribution
The difference between internal and external validity is in their nature. Internal validity indicates if a study depicts relation between two variables. External validity on the other hand generalizes the study of the variables.
urmmm .. shows cause and effecthas high control which lead to high reliability & validity
differences between errors and frauds
Differences between Classification and Tabulation
One of the basic differences between science and pseudoscience is a lack of empirical research. Empirical research must meet the rigors of validity and reliability criteria to be considered science.
Considering in test-scoring "reliability" refers to the consistency of the test scores, and "validity" refers to the accuracy of the interpretations made from those scores, then reliability is possible without validity, although validity is not possible without reliability.

Explain the concepts of reliability,
relibality
The characteristics of evaluation are: validity and reliability
Norms reliability validity
validity and reliability
to test if they are measuring what they supposed to measure.
Double checking and verification are some of the procedures that can be followed by an organization to ensure reliability,validity and accuracy of the data information.
1.Reliability 2.Validity 3.Practicality
There is none You're stupid why would you ask that !!!!!!!!!!!!!!!!!!!!!
