    Question 2 independent var, 1 dependent var. What test should I use? Help wanted please!




    I desperately need some help with my research please.

    I am researching the effect of instruction in primary school and secondary school. My aim is to find out whether it is better to give instruction in English or Dutch.

    Both the primary school and the secondary school are divided into three groups:
    1. English instruction
    2. Dutch instruction
    3. No instruction

    All groups took thee tests: 1 pre instruction and 2 post instruction tests.

    I used Kruskal-Wallis to answer my question, but it didn't give me the results I'm looking for. It either gives me test results for primary school and secondary school or instruction type (see attachment); but what I need is results like:

    Primary school, test 1 English instruction
    Primary school, test 1 Dutch instruction

    and so on.

    My questions:

    1. Is Kruskal-Wallis the right test to use? If so, how do I get the results I need?
    2. Should I use a different test?

    I reaaly hope someone can help me with this problem. Thanks anyway!
