    • What is a Type I error?
      When the psychologist rejects the null hypothesis (so accepts experimental hypothesis)
    • give details about a type I error?
      In reality there was not a significant relationship or difference between what was being investigated so they should have accepted the null hypothesis but did not
    • when could Type I errors happen?
      When you run the statistical test using a sig level that is too lenient eg p<0.1 or the 10% level
      • you're essentially allowing here for 10% of the time your results are actually due to chance but can still report that they are statistically significant
    • type 1 means significance level is ?
      too LENIENT
