    How to prove the we have very similar 2 tests grades ?

    Hi,


    If we students grades in test 1 and 2
    Test1 - Test2
    100 - 100
    99 - 99
    98 - 98
    97 - 98
    96 - 95
    95 - 93


    How to show that these 2 tests are similar? show that there is no significance difference between 2 tests and then show that they have high Spearman correlation?

    Many thanks

    Hey zia.

    Have you heard of the Pearson Chi-Square test?

    Chi-square can't solve this numerical , since it needs ordinal data.
