• You get the data.
  
  
• You calculate the mean and standard deviation.
  
  
• You calculate the t-ratio.
  
  
• You look it up.
  
  
• If the probability of t is less than .05 or .01, you have significance.
  
  
• You conclude the group is different from the Null Hypothesis mean.

REMEMBER THIS:

• Big t (absolute value)
• Small p
• Small p = significance
