  3. 標準偏差計算機用於計算一組數字的均值,方差和標準差 (分步驟顯示計算過程)。 標準偏差是統計和概率理論中廣泛使用的變異性或多樣性測量。 它顯示了數據的精確程度。 標準差是其方差的平方根。 低標準偏差表示數據點傾向於非常接近平均值,而高標準偏差表示數據分布在大範圍的值上。 方差和標準差取決於一組數字的平均值。 計算它們取決於集合是人口還是樣本。 人口的變異與標準差. 總體標準差衡量數據的可變性。 它通常是一個未知的常數。 人口的方差σ 2 和標準偏差σ由下式給出: 其中: σ=總體標準差. σ 2 =總體方差. x 1 ,...,x N =總體數據集. μ=總體數據集的平均值. N =人口數據集的大小. 樣本的方差和標準偏差. 樣本標準差是基於樣本的總體標準差的估計。

  4. 我們的線上標準差計算器可確定給定資料集的標準差、平均值、變異數、總和、變異數係數、統計總體和誤差範圍。 我們的 SD 計算器可讓您快速計算並給出準確的結果。 什麼是標準差? “標準差是對給定組或一組值之間差異的測量。 標準差越低,表示數值越接近集合的平均值。 高標準差表示值分佈在更廣泛的範圍內。 標準差公式: 我們的線上平均值和標準差計算器透過使用以下等式使標準差計算快速且準確: s = \sqrt {\dfrac {1} {N – 1} \sum_ {i=1}^N\left (x_ {i} – \bar {x}\right)^2} s = N –11 i=1∑N (xi–xˉ)2. 總體標準差公式為:

    2023年6月5日 · The standard deviation is a measure of the variability in a dataset. In other words, the standard deviation describes how "spread-out" the data is around the mean. This calculator deals with separate data points, but we also have a dedicated grouped data standard deviation calculator for ranged data.

  10. Standard deviation measures a data set's average dispersion/deviation/variability relative to the mean. It is often denoted by the Greek letter σ for a population or s for a sample. A larger value of σ or s implies a larger dispersion of data points from the sample mean and vice versa.
