The z-score, also known as the standard score, is a measurement used in statistics. It is the measurement of the number of standard deviations that a specific number is above or below a mean. The formula to calculating the z-score is:

z = (x – μ) / σ

where:

• z is the z-score,
• x is the value to be standardized,
• μ is the mean of the given set of data,
• σ is the standard deviation of the given set of data.

The Ishikawa diagram, popularly known as the fishbone diagram or the cause and effect diagram, is mainly used in quality management. It is used to analyze inefficiencies of processes. Thanks to the fishbone diagram, we have the opportunity to analyze the problem that is visible in the process.

The Ishikawa Diagram is a tool that will detailly identify the root causes of this problem. In other words, an ishikawa diagram can help identify defects in processes by analyzing the root causes of the problem.

Trigonometry is a branch of mathematics that studies the relationships between the elements (sides and angles) of a triangle.

You may recall many trigonometric formulas and equations from your school or college days. Some of them are cot x = 1/tanx , six x/cos x = tan x, sin(900-x) – cos x and so on.

Excel offers a number of built-in functions that deal with trigonometry. You can use these trig functions to solve complex trigonometric expressions.
