The mean: To determine the mean, first add numbers and then, divide via the number of numbers in a group. Mean is also known as average.The mode: To determine the mode, first place the numbers in order from lowest to highest, and then count the number of times each of the numbe...
将频率列中的值相加。 n=1+3+9+2=15n=1+3+9+2=15 均值(mu) 为f⋅Mf⋅M的和除以nn,即为频率的和。 μ=∑f⋅M∑fμ=∑f⋅M∑f 平均值是中点和频率的乘积之和除以频率总和。 μ=31515μ=31515 化简μ=31515μ=31515的右边。 2121...

Systematic lidar observations of Saharan dust over Europe in the frame of EARLINET (2000–2002) The center of mass of these layers was located in altitudes between 850 and 8000 m. However, the mean thickness of the dust layer typically stayed ... A.,Papayannis,V.,... - 《Journal of Ge...
m = mean(array) variance = array.inject(0) { |variance, x| variance += (x - m) ** 2 } return m, Math.sqrt(variance/(array.size-1)) end #All the items in the list are close to the mean, so the standard #deviation is low. ...
In this lesson, we will discuss how to find the period of a sinusoidal function (that is, the period of a sine wave). However, let us first consider what we mean by the period of a function. In any function which repeats itself, there will be a point where the function's value ...
