To understand this we need to appreciate the symmetry of the standard normal distribution curve. We are trying to find out the area below: But by reflecting the area around the centre line (mean) we get the following: Notice that this is the same size area as the area we are looking ...
The equation to find the normal distribution in a set of data is given below. Where, σ = Standard Deviation x = Sample Data μ = Average/Mean In practical terms, the normal distribution helps us understand the significance of data within a group. Now, let’s look at how to find the ...
You’re probably familiar with data that follow the normal distribution. The normal distribution is that nice, familiar bell-shaped curve. Unfortunately, not all data are normally distributed or as intuitive to understand. You can picture the symmetric normal distribution, but what about the Weibull...
For example, if you had data from a normal distribution with a mean of 50 and a standard deviation of 10, then 68% of the distribution would be between 50 – 10 = 40 and 50 +10 = 60 [1]. We know this because of theempirical rule(aka the 68-95-99 rule). The variance does no...
Another key to progress in most digital transformations is tapping talent with the right experience to complement the knowledge of those who understand distribution. As one executive that is focusing on bringing in external talent said, “You are one good person f...
