Skewness

Skewness

Dalam teori kebarangkalian dan statistik, skewness adalah ukuran dari asimetri dari taburan kebarangkalian pemboleh ubah rawak yang bernilai sebenar tentang min. Nilai skewness boleh positif atau negatif, atau bahkan tidak jelas. Tafsiran kualitatif yang condong itu rumit. Untuk pengedaran unimodal, condong negatif menunjukkan bahawa ekor di sebelah kiri fungsi ketumpatan kebarangkalian lebih panjang atau lebih gemuk dari sisi kanan - ia tidak membezakan bentuk ini. Sebaliknya, condong positif menunjukkan bahawa ekor di sebelah kanan lebih panjang atau lebih gemuk daripada sisi kiri. Dalam kes di mana satu ekor panjang tetapi ekor yang lain adalah lemak, kecenderungan tidak mematuhi peraturan yang mudah. Sebagai contoh, nilai sifar menunjukkan bahawa ekor di kedua-dua belah keseimbangan min, yang mana kedua-duanya untuk taburan simetri, dan untuk pengedaran asimetik di mana asimetri bahkan keluar, seperti satu ekor yang panjang tetapi nipis, dan lain yang pendek tetapi gemuk. Selanjutnya, dalam pengedaran multimodal dan pengagihan diskret, skewness juga sukar difahami. Yang penting, skewness tidak menentukan hubungan min dan median.

In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive or negative, or even undefined. The qualitative interpretation of the skew is complicated. For a unimodal distribution, negative skew indicates that the tail on the left side of the probability density function is longer or fatter than the right side – it does not distinguish these shapes. Conversely, positive skew indicates that the tail on the right side is longer or fatter than the left side. In cases where one tail is long but the other tail is fat, skewness does not obey a simple rule. For example, a zero value indicates that the tails on both sides of the mean balance out, which is the case both for a symmetric distribution, and for asymmetric distributions where the asymmetries even out, such as one tail being long but thin, and the other being short but fat. Further, in multimodal distributions and discrete distributions, skewness is also difficult to interpret. Importantly, the skewness does not determine the relationship of mean and median.
