A test of statistical significance indicates how confident the researcher is about :

  • A.Collecting data properly
  • B.Inter-tester reliability
  • C.Understanding the data analysis
  • D.Generalizing their findings from sample to population

Answer: D

It indicates confidence in Generalizing their findings from sample to population.

A significance test asks how likely it is that a result found in a sample, such as a difference between groups, arose by chance. A significant result (for example p less than 0.05) lets the researcher infer, with a stated level of confidence, that the effect exists in the population from which the sample was drawn.

It says nothing about whether data were collected properly, about inter-tester reliability, which is checked separately, or about the researcher's understanding of the analysis.
