00:00:00,15 --> 00:00:04,41
Listening to Euphonium and if we're
looking at alpha, we can see
2
00:00:04,42 --> 00:00:07,74
a mean of 9.7 and
3
00:00:07,75 --> 00:00:14,07
a standard deviation of 8.5.
Now if we take the same subject,
4
00:00:14,58 --> 00:00:20,20
F1 listening to cello, we have alpha, here
5
00:00:20,21 --> 00:00:26,08
a mean of 6.7 and
6
00:00:26,09 --> 00:00:32,67
a standard deviation of 3.9. If we're using
7
00:00:33,50 --> 00:00:39,06
the calculation method of entering
the mean, standard deviation, and N
8
00:00:40,27 --> 00:00:47,22
assuming here one data point per second
for 60 seconds and we must use
9
00:00:47,23 --> 00:00:48,78
unpaired T test
10
00:00:48,79 --> 00:00:54,79
because we're not in putting the
individual values. We'll calculate now and we
11
00:00:54,80 --> 00:00:59,91
get by conventional criteria: the difference
is considered to be statistically
12
00:00:59,92 --> 00:01:01,93
significant with a P
13
00:01:01,94 --> 00:01:06,29
value of 0.0144.
14
00:01:11,04 --> 00:01:17,96
Oh. The aplha was higher while
listening Euphonium. The mean is
15
00:01:17,97 --> 00:01:22,47
9.7 for Euphonium and cello 6.7.
