1 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.
