CSS is a powerful tool which enables developers to customize the appearance of websites according to their will. Since, there are numerous features and properties provided by CSS, it is quite possible that the developers use two keywords interchangeably in order to achieve a desired effect. So, it is important to know about such confusing keywords in detail to avoid further mistakes. Two such keywords are “revert” and “unset”. These two may appear similar, but have noticeable differences for some properties for certain elements. Here, we will discuss about these keywords, how and when to use them, and differences between ... Read More
In today’s era of web designing, the creation of visually attractive websites with proper layouts and organized content is the key task. One of the most commonly faced challenges is that the developers need to know how to properly define the space between the elements so as to increase the readability of the webpage. Here, we have CSS for the rescue. CSS enables the developers to control the appearance of HTML elements, including proper spacing between them. In this article, we will discuss different methods used for setting the vertical space between the list of items using CSS. We ... Read More
Cascading Style Sheets (CSS) is fundamental language used for styling the webpages during web development. It enables the developers to customize the layout and add visual effects to it. CSS Selectors are an important tool which allows the developers to select or match HTML elements and apply styles to them. :first-child and :first-of-type are most commonly used selectors which are often confused by the developers. Some may have used them interchangeably by mistake. Although they look quite similar when applied to elements, there are few differences which may impact your web design (if not used appropriately). In this article, ... Read More
Introduction Machine learning is a common topic in the technology and business world. Machine learning is a technology that processes the raw data, provides helpful information, including data prediction and analysis, and releases final statistics reports. In short, ML helps process the data and produces reports to achieve the set goals. It uses various high-end algorithms and paradigms to engage with the solutions. Artificial Intelligence is the fastest-growing technology under which machine learning and deep learning work. In this article, you will see the top 7 hackathons and technical events of machine learning, that are organized worldwide. This includes ... Read More
Introduction The Grubbs test is a statistical hypothesis testing method to detect outliers in a dataset. Outliers are the observations that disburse the data distribution and are also known as anomalies. The dataset with outliers tends to overfit more than data with a Normal/Gaussian distribution. Hence, it is necessary to tackle the outliers before Machine Learning modeling. Before handling, we must detect and locate the outliers in the dataset. The most popular outliers detection techniques are QQPlot, Inter-Quartile range, and Grubbs statistical test. However, this article will discuss only the Grubbs test to detect the outliers. You will learn: what ... Read More
Statisticians use F-test to check whether the two datasets have the same variance or not. F-test is named after Sir Ronald Fisher. To use the F-Test, we make two hypotheses, a null hypothesis, and one alternate hypothesis. Then we select any of these two hypotheses approved by the F-Test. Variance is a data distribution metric to tell the data deviation from the mean. The higher values show more dispersion than the smaller values. In this article, you will learn how to perform an F-Test in Python programming Language with its use cases. F -Test Process The process to perform the ... Read More
Introduction Data Scientists often use statistical methods for hypothesis testing to gain insights from the datasets. While there are multiple statistical methods available, this article will discuss the Chi-Square Goodness of fit test with its implementation in Python. The Chi-Square test validates the observed distribution of categorical variables to the expected distribution. It tells us if the available event values differ from the expected values. Chi-Square Test You can perform the Chi-Square test to verify the dataset distribution for observed events. The Chi-Square test makes some assumptions which are as follows − Variables are independent. Only one categorical feature ... Read More
The Brown-Forsythe test is a statistical test used to determine whether the variances of two or more groups are equal. While Levene's test uses the absolute deviations from the mean, the Brown-Forsythe test uses the deviations from the median. The null hypothesis used in the test is as follows − H0: The variance of the groups (populations) is equal The alternative hypothesis is that the variances are not equal − H1: The variance of the groups (populations) is not equal To perform the test, we calculate each group's median and the absolute deviations from the median. Then we calculate the ... Read More
Traditional marketing refers to any type of marketing that existed before the advent of the internet and digital technologies. This includes advertising through print media such as newspapers, magazines, billboards, and flyers, as well as broadcast media like television and radio commercials. Traditional marketing also includes direct mail, telemarketing, and event sponsorships or promotions. The goal of traditional marketing is to reach a large audience through mass media channels and persuade them to purchase a product or service. While traditional marketing can be effective, it can also be costly and difficult to measure the return on investment (ROI). About ... Read More
