• Example answer

  
• How to calculate pt1

  -assign positive and negative signs depending on the flow of direction (if answer is the same for both conditions = ignore) e.g Yes to condition A + no to condition B = +, no to condition A + yes to condition B = -

  -count the number of positive and negative signs

  -use the smallest No as observed value - if observed value is less than critical value, the results are significant

  
• How to calculate pt2

  the least frequent sign is the observed value

  
• To read a critical values table we need to know:

  -the level of significance

  -the number of Ps whose scores were used
