    What does this t-test tell you?

    This is the result of a matched pairs t test, to test if childrens maths scores have decreased.

    P-value is 1, does this mean that there is absolutely no change in scores, or just that the hypothesis that μ is equal to 0 cannot be rejected.

    I'm so confused, what would you conclude?

    Output below:

    Hypothesis test results:
    μ : mean of Variable
    Ho : μ = 0
    Ha : μ < 0

    Sample Mean: 6.78

    Std. Err: 0.9084986

    DF: 99

    T-Statistic: 7.4628625

    P-value: 1

    It means that the t-statistic is so large that there is virtually no chance that the null hypostheis could give rise to the data by chance if the test has been performed correctly.
