Normality Test in Minitab: Minitab with Statistics
Normality is a key notion in statistics that is employed in a variety of statistical procedures. The normality test determines whether or not data follows a normal distribution. A normal distribution is a symmetric bell−shaped curve around its mean. Because approaching normality occurs spontaneously in many physical, biological, and social measuring circumstances, the normal distribution is the most frequent statistical distribution. Many statistical studies demand data from regularly distributed populations. Minitab may be used to run a normality test. Minitab has statistical tools that make it simple to do statistical computations. Let's look at how to do a normalcy ...
Read MoreNeeds and Strategies for the Six Sigma Control Plan
Six Sigma methodologies are well−known for their data−driven, logical approach to problem−solving. What truly separates them from other quality theories is their adaptation and usefulness outside manufacturing, where they were born. One of the key objectives of Lean Six Sigma is to reduce unnecessary phases and waste in a process or business model. The lean approach eliminates any process that offers no value to enhance efficiency, workflow, and profitability. Organizations create Control Plans to help management monitor measurements, document accomplishments, and make changes for continuous process improvement. A Control Plan is a method of documenting the functional parts of ...
Read MoreCan I use a JavaScript variable before it is declared?
Yes, you can use a JavaScript variable before it is declared, with a technique called hoisting. The parser reads through the complete function before running it. The behavior in which a variable appears to be used before it's declared is known as hoisting. For example, the following, rank = 5; var rank; The above works the same as the following − var rank; rank = 2; Hoisting in JavaScript, allows us to declare variables, functions, or classes that are moved to the top of the scope preceding the execution of the code regardless of whether their scope ...
Read MoreFind digits not between the brackets using JavaScript Regular Expressions?
In JavaScript, the regular expression [^0-9] is used to find the characters inside the bracket but not a digit. Except digit mentioned in the bracket, it will return the remaining characters from the text as an array. We all know about RegExp (Regular Expression) in JavaScript.

Read More5 Lean Principles to Enhance Your Project Efficiency
Toyota's manufacturing division developed the lean approach, but it soon became apparent that project managers could use lean concepts to decrease waste and inefficiency in any business. From healthcare to software development, lean concepts reduce costs while maintaining a competitive advantage. For many American businesses, being lean is the only way to compete globally against competitors from nations with substantially cheaper manufacturing costs. Lean has shown to be an efficient approach to managing teams in some of the most demanding sectors, including software development, manufacturing, and construction. The fact that the technique is simple to comprehend and quick to make ...
Read MoreAre both addition and concatenation same in JavaScript?
We can't say whether both are the same or both are different. In some cases, addition and concatenation will have the same result, but in some cases, they will be different. It is completely based on the type of variables. We will see it in detail below We use the + operator for addition and the concat() method for concatenation in JavaScript. In some cases, both the + operator and the concat() method returns the same result. Adding and concatenating two strings using the + operator and the concat() method returns the same result. We can also apply the ...
Read MoreHow to convert a value to a number in JavaScript?
In this article we are going to discuss how to convert a value to a number in JavaScript. JavaScript has introduced Number(), parseInt(), parseFloat() methods to convert a value into a number and also we can achieve it by using (+) unary operator. These mentioned methods can convert number strings to numbers and Boolean values to 1's or 0's. Let’s us discuss these above mentioned methods briefly. We’ll discuss the 4 possible ways to convert a value to a number with an example each. Number() parseInt() parseFloat() Unary Opertaor(+) Example 1 The following is an example program to ...
Read MoreHow to set dynamic property keys to an object in JavaScript?
In the following example we are going to learn how to set dynamic property keys to an object in JavaScript. To add dynamic property keys to an object in JavaScript, there are three possible ways. There are three possible ways to set dynamic property keys to an object.

Read MoreHow to access an object value using variable key in JavaScript?
In this article we are going to discuss how to access an object value using variable key in JavaScript. An object value can be accessed by a Dot Notation and a Bracket Notation. To get the object value through a variable key, the value or expression inside the bracket notation must match with the existing key name, then it returns a value. The bracket notation, unlike the dot notation can be used with variables. If we are using a variable with bracket notation, the variable must reference a string. Let’s understand this concept better with the help of examples further ...
