Variable sampling is used for measurement of hardness , tensile strength , resistance and other physical properties of the desired sample. The variables used for measurement are on a continuous scale and the limits for rejection are clearly demarcated for the entire range. The sample which is t...
As some statistical tests, such asmultiple linear regression,ttest, orANOVA, can only be applied to a sample size large enough to approximate the true distribution of the population, using probability sampling allows you to establish correlation or cause-and-effect relationship between your variables...

A sampling distribution is the frequency distribution of a statistic over many random samples from a single population. Sampling distributions are at the very core of inferential statistics but poorly explained by most standard textbooks. The reasoning may take a minute to sink in but when it does...
For example, gender isa nominal variablethat can take responses male/female, which are the categories the nominal variable is divided into. How do you control extraneous variables? One way to control extraneous variables iswith random sampling. Random sampling does not eliminate any extraneous variabl...
Ordinal data is a type of statistical data where the variables are sorted into ranges, and the distance between the ranges are not known. Think of the pain scale they sometimes use in the hospital, where you judge the level of pain you have on a scale of 1-10, with 1 being low and...

‘Quantitative data’ can be understood as something that can be counted and measured. It is a simple concept that offers insight into the number of required variables. As a business, you have been usingqualitative datafor different purposes. Think of the time when you wished to knowhow many...
Because the normal distribution is continuous, we can’t just add probabilities as we do with discrete variables. We instead use integration to find the area under the curve, which is the probability. The integral of the PDF between two values (x1 and x2) gives the probability that the ran...
Causal AI is a branch of AI that focuses on clarifying and modeling causal relationships between variables, rather than merely identifying correlations. Traditional AI techniques, such as ML, often rely on statistical correlation to make predictions. Causal AI instead aims to find the underlying mech...
