Hi,

I have data where I have compared the means and from visualising it I can see that one group have lower values than the other, however I am not sure how to quantify this so that I can say whether group 1 has slightly lower scores or much lower scores.

Here is my table:
Age Group 1 (males) Group 2 (males) Group 1 (females) Group 2 (females)
40-44 37.3 50.3 25.8 30.7
45-49 36.6 48.8 20.1 29.9
50-54 35.9 47.6 18.5 28.7
55-59 34.3 46.2 21.2 27.5
60-64 30.3 44.6 19.2 26.5
65-69 31.5 42.3 18.8 25.3
70 23.6 39.1 10.5 23.5
