the sign test

• 1. work out the sign (+ or - difference)
  2. add pluses add minuses
  3. s (calculated value) = least frequent sign
  4. n = total number of scores (ignore the 0s)
• answer structure

  when n = at the 5% level the critical value of a one/two tailed test is ....

  this is less/more than the calculated value , in order to be significant the calculated value must be equal to or less than the critical value and therefore the data is signficant/not significant and the null hypothesis should be accepted/ rejected
