[00:00:06.920]We are going to create a line graph in Excel
[00:00:09.680]of the mean for the percent greenness for all three
[00:00:12.730]of our buffalograss genotypes.
[00:00:15.010]So what we eventually are going to come up with
[00:00:17.470]is this graph right here.
[00:00:19.810]So the first thing that we have to do is find our mean
[00:00:23.510]and round it to the 10th decimal place.
[00:00:26.030]And that'll be this first video.
[00:00:27.770]So I'm gonna break it into two parts.
[00:00:29.320]The next video will be how to create our perfect line graph
[00:00:33.200]for our genotypes.
[00:00:34.890]So we are going to start right up here
[00:00:37.730]and I have all three of my buffalograss genotypes.
[00:00:41.420]And I have all the data collected for each date in 2015.
[00:00:47.300]And I have all three repetitions.
[00:00:50.750]So our first step is to calculate the mean.
[00:00:53.780]So I have created a column for the mean
[00:00:57.760]and so you'll be able to see it easily.
[00:01:00.680]I know that these two dates in April
[00:01:02.350]are both going to be zero.
[00:01:04.590]So I'm going to start for May 11th.
[00:01:07.550]And to calculate the mean,
[00:01:09.150]you would hit equals, average, open parenthesis,
[00:01:14.500]and then you will highlight the cells
[00:01:17.140]that you want calculated and you hit enter.
[00:01:20.330]And there you have your mean.
[00:01:22.660]And so to get the mean for the other dates,
[00:01:25.740]all I have to do is click and drag down
[00:01:29.600]and it'll automatically calculate that for me.
[00:01:32.890]And so to round our mean, I know those are zero.
[00:01:37.790]All I do is I hit equals, round, open parenthesis,
[00:01:44.260]highlight my mean, you're gonna put a comma and a one.
[00:01:49.440]And so one signals to round one spot to the right
[00:01:52.460]of the decimal place.
[00:01:53.960]So if I put a two there instead,
[00:01:56.340]that would signal it to round two spots
[00:02:01.040]to the right of the decimal place.
[00:02:02.560]So we want the 10th, so we only want one.
[00:02:05.280]Close my parentheses and I hit enter
[00:02:09.010]and my data is rounded to the 10th decimal place.
[00:02:13.260]And then all I do is click and drag down again.
[00:02:16.470]And all of my mean
[00:02:18.020]for this genotype of buffalograss is rounded.
[00:02:22.160]And so then you would do that
[00:02:23.850]for your other two buffalograss genotypes
[00:02:27.140]and then in the next video, we will take this data
[00:02:30.810]and we will create a line graph for it.
