wilcoxon sign ranks test

• criteria for using the wilcoxon signed ranks test:

  • DV = produces ordinal/interval data
  • research design = repeated measures design
  • explores a difference between each condition
• what does it mean when the observed value is greater than or equal to the critical value?

  the results = NOT significant so null hypothesis accepted + alternative = rejected
• what does it mean when the observed value is less than or equal to the critical value?

  the results = SIGNIFICANT so null hypothesis rejected + alternative = accepted
