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

  • A.the inter coder reliability of their structured interview schedule
  • B.Passing the driving test
  • C.Understanding the differences between bi-variate and multivariate analysis
  • D.Generalizing their finding from the sample to the population

Answer: D

It indicates confidence about generalizing their finding from the sample to the population.

A test of significance asks how likely it is that a result found in the sample, such as a difference or correlation, arose by chance from sampling. A significant result, for example at the 5 per cent level, lets the researcher infer with stated confidence that the result holds in the population from which the sample was drawn.

Inter-coder reliability is measured with agreement statistics such as Cohen's kappa, and understanding bivariate and multivariate analysis is a matter of method, not of testing. Passing the driving test is an unrelated distractor.
