Std.Deviation是标准差 variance是方差
Find out the Mean, the Variance, and the Standard Deviation.Your first step is to find the Mean:Answer:Mean = 600 + 470 + 170 + 430 + 3005 = 19705 = 394so the mean (average) height is 394 mm. Let's plot this on the chart:...
I have to write a program to calculate sum, mean, variance, and standard deviation and I was able to do the sum and mean but I don't understand the variance and standard deviation. If the size of the set is 7 and the set is represented by X[0], X[1], X[2], X[3], X[4]...
In your work as a data analyst, you may frequently be up against heaps of numerical data. A typical first step in making sense of a large data set is calculating some descriptive statistics, such as the mean, median, mode, variance and standard deviation, among o...

- **A. Std.Deviation**:标准差(Standard Deviation)的英文缩写即为Std.Deviation,直接对应。 - **B. Sum**:表示数据的总和,与标准差无关。 - **C. Mean**:表示数据的平均值,与标准差无关。 - **D. Variance**:表示方差,是标准差的平方,但并非标准差本身。 因此,正确答案为A。题目完整且选项明确,...
Standard Deviation - Machine Learning By: Rajesh P.S.Variance serves as a measure of the dispersion or spread of data within a dataset. It quantifies the average of the squared differences between each data point and the mean of the dataset. By squaring the differences, the variance ...
