Statistics is a specific academic field in which data is collected and analyzed. There are many specific types of statistical analyses, all varying depending on the type and amount of data being analyzed. Statistics is also commonly used in a variety of academic settings for research purposes,...
This is becoming more important day by day as the competition increases it becomes imperative for the companies to use the resources that they have in the beat possible manner. When every strategy implementation costs you large amount of money; your whole objective is to improve the return ...
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...
This means that the variation in the timing of a specific logic transition from the ideal time is centered at zero, can occur arbitrarily early or late, but nearly always occurs within a few units of sigma from the ideal. Sigma, or σ, is the width of the Gaussian distribution. It's ...
Lean thinkers implement multiple methods of continuous improvement like, “Six Sigma, Lean, Kaizen, and lean management in their business practices. These methods address weak points and strategically assess their productivity and profitability based on systematic cycle times. ...
Answer and Explanation: a) The method of analyzing data to infer characteristics of an underlying distribution of probability is known as the Statistical Inferences. This...
- varianceσ i 2 {\displaystyle \sigma _{i}^{2}} , all having the same mean, one possible choice for the weights is given by the reciprocal of variance:...- In statistics, the variance inflation factor (VIF) is the ratio (quotient) of the variance of a parameter estimate when **...
Statistics [ONS],Citation2023). The South African Police Service Annual Crime Report for the year October 2022 to December 2023 shows that there were 15,284 sexual assault cases reported to the police in South Africa (South African Police Service [SAPS],Citation2023). Of those sexual assault ...
Standard deviation is an essential tool for measuring dispersion in a distribution. The square root of the arithmetic mean of the squares of deviations of observations from their mean value is the standard deviation. It is commonly denoted by sigma, i.e. σ. It should be noted that, unlike ...
RCA is one of the primary tools used in Six Sigma DMAIC. A thumb rule in this process is repeatedly asking “why” which will subsequently reveal the underlying root cause beneath the symptoms. Eg: A person is on his way to office and the car stops in the middle of the road....
