A critical value is the test statistic’s value that establishes a confidence interval’s upper and lower boundaries. It explains how far away from the distribution’s mean you must be to account for a specific percentage of the overall variation in the data. For instance, 90%, 95%, and 99%. Your critical value will be the same …

जब हम किसी संख्या को निश्चित संख्या तक उसी से लगातार गुणा करते हैं, तो इन संख्याओं को उपयुक्त और सुविधाजनक रूप में लिखने के लिए घातांकों का उपयोग किया जाता है। गणित में, हम बड़ी गणनाओं को हल करने के लिए घातांक के विभिन्न नियमों का उपयोग करते हैं। इस भाग में हम वास्तविक …
When we multiply a number continuously by itself till a certain number, then exponents are used to writing these numbers in a suitable and convenient form. In mathematics, we use different laws of exponents to solve large calculations. In this section, we will study different laws of exponents for real numbers. Before understanding the laws …
इस भाग में, हम वास्तविक संख्याओं पर विभिन्न गणितीय संक्रियाओं जैसे कि जोड़, घटाव, गुणा और भाग का अध्ययन करेंगे। हम जानते हैं कि परिमेय संख्याएँ और अपरिमेय संख्याएँ वास्तविक संख्याएँ होती हैं इसलिए हम उन पर संक्रियाएँ लागू करेंगे। परिमेय संख्याओं के लिए जैसा कि हमने पिछली कक्षाओं में सीखा है, परिमेय संख्याएँ योग …

In this section, we shall study different mathematical operations on real numbers such as addition, subtraction, multiplication, and division. We know that rational numbers and irrational numbers are real numbers so we’ll apply operations on them. For Rational Numbers As we have learnt in previous classes, rational numbers satisfy the commutative, associative, and distributive properties …
Calculus is a branch of mathematics that deals with rates of change and curvature of functions. Derivative (Differential) calculus is a subfield of calculus that deals with the study of derivatives. In other words, it’s the study of how a function changes when its inputs are changed. In this blog post, we’ll break down everything …

The variance is a widely used concept in probability and descriptive statistics for measuring the variability of the given data. The variance is a technique for determining the various terms in finance. It is just the same as the standard deviation but it is measured in squared units. Let us explore the term variance. What …

पिछली कक्षाओं की जानकारी के अनुसार, हम संख्या रेखा पर विभिन्न प्रकार की संख्याओं के निरूपण से परिचित हैं जैसे प्राकृत संख्याओं, पूर्ण संख्याओं, पूर्णांकों और परिमेय संख्याओं के निरूपण से। इस भाग में, हम अपरिमेय संख्याओं सहित संख्या रेखा पर वास्तविक संख्याओं के निरूपण (Representation of Real Numbers on the Number Line) के बारे …
As per the knowledge of the previous classes, we are familiar with the representation of different types of numbers on the number line like the representation of natural numbers, whole numbers, integers, and rational numbers. In this section, we’ll learn the representation of real numbers on the number line including irrational numbers also. We’ll represent …
