In this endocrinology study, four different variables were measured and tracked, which are the lines on the graph, after injections of various hormones.
00:14
So what we're going to do is label the graph and go over when these injections occurred and kind of explain based on the change in variables how we can figure out which injection happened when.
00:26
So first of all, the four variables tracked were the follicle -stimulating hormone, which is normally in terms of its units anywhere between 1 and 7.
00:42
Sperm density, which can be anywhere between 30 and 50.
00:49
Lutonizing hormone, which is anywhere between 1 and 7 .8, and then testosterone, which is usually anywhere between 500 and 800.
01:06
All right, so we're going to think about how these scales relate to the graphs up above, because there are different scales on the left side.
01:14
And then how the change in those variables is related to the injections.
01:18
So first, let's label the lines.
01:22
So testosterone is the lowest graph.
01:34
Lutonizing hormone is the second.
01:38
And i believe this is sperm count.
01:43
And lastly, f -sv6.
01:46
Fsah.
01:48
And partly, this can be explained by, you know, the scale as well as the response to the injections...
