Hi, Nice to meet you all. This is the first time I visit this forum.

I have a few questions about what statistical method I should be using and therefore I sincerely hope someone can help (greatly appreciated.)

I am required to compare the mean of differents test to see are there any significant difference in mean. The data may or may not be normally distributed.

e.g. test 1, 3.45
test 2, 9.99
test 3, 7.49
test 4, 1.87

I have tried to research and find a few test, they are t-test and ANOVA (one way and two way), however, I am not quite sure which one would be an appropriate option.

Again, many thanks for your kind help,

steven
