Analyse statistique des mesures de spores.
Lunghezza (N = 30) Mean = 10.183 Variance = 0.508 Std.Dev. = 0.713
Std.Error of Mean = 0.130
0.950 Confidence Interval for mean : 9.917 to 10.450
Skewness = 0.671 Std. Error of Skew = 0.427
Kurtosis = 2.179 Std. Error Kurtosis = 0.833
Larghezza (N = 30) Mean = 8.833 Variance = 0.584 Std.Dev. = 0.764
Std.Error of Mean = 0.140
0.950 Confidence Interval for mean : 8.548 to 9.119
Skewness = -0.135 Std. Error of Skew = 0.427
Kurtosis = 3.682 Std. Error Kurtosis = 0.833
La moyenne réelle des longueurs fluctuera donc entre 9,92 et 10,45 µm; celle de la largeur comprise entre 8,54 et 9,12 µm.
