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 More
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 More
In this tutorial, we are going to learn about how to calculate days from epoch using JavaScript. Here, we are going to use the Math.abs() and the Math.floor() methods to calculate days. First, we are going to learn about what an epoch is. What is Epoch? It is also referred to as epoch time or Unix time or Posix time. In a determining context, an epoch is the data and time relative to which a computer's clock and timestamps are determined. An epoch time is the number of seconds that have elapsed since Jan 1st, 1970 at midnight ... Read More
In this tutorial, we will see how to find a word character from the text. Word character denote as \w. Word character is a character like a-z, A-Z and 0-9 and also includes underscore(_). We all know about RegExp (Regular Expression) in js. RegExp is an object and specifies the pattern used to do search and replace operations on string or for input validation. RegExp was introduced in ES1 and it is fully supported by all the browsers. ASCII code for A-Z is 65- 90, a-z is 97-122, 0-9 is 48-57 and for underscore is 95. Syntax Syntax for word ... Read More
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 ...

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. RegExp is an object that specifies the pattern used to do a search and replace operations on the string or for input validation. RegExp was introduced in ES1 and it is fully supported by all browsers. Syntax Syntax for non-digit or /[^0-9]/ character is- new RegExp("[^0-9]") or simply /[^0-9]/ Here /[^0-9]/ , ... Read More
Today's interconnected, fast−paced commercial environment demands fierce competition from modern organizations. Because every competitive advantage counts in this environment, business professionals are constantly researching novel management methods. But the ideal solution might not come from a novel approach. Combining the tried−and−true Lean method with the Six Sigma approach may be the key to success as businesses optimize their processes for maximum efficiency and strive to uphold high−quality standards. What is Lean Six Sigma? Lean Six Sigma is a team−oriented management technique aiming to increase performance by removing waste and resource faults. It blends Six Sigma methodology and tools with the ... Read More
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 More
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 More
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 More
