  • Each participant is measured on two or more different occasions

  • e.g. time 1/time 2; before/after

  • Research question: Is there a charge across time?

  • Example research question:

    • Does treatment make a difference?

Related samples t-test

  • Is there a significant difference between the means at time 1 (before) and at time 2 (after)?

  • Null hypothesis (no effect, no difference)

    • H0:u1=u2

  • or H0=u1-u2=0

  • Alternative hypothesis (of effect)

    • H1:u1-u2=/0
