Today, I collected everything you want to know about data visualization, including the definition, importance, and basic types. Also, I will introduce the top 16 types of charts in data visualization and analyze their application scenarios to help you quickly select the type of chart. In the ...
So while the average of the data might be 65 out of 100, there can still be data points at both 1 and 100. Measures of variability help communicate this by describing the shape and spread of the data set. Range,quartiles, absolute deviation, and variance are all examples of measures of...
In simple terms, Discrete data is countable and Continuous data is measurable. Let’s explore the two types of data in detail. Discrete data is data that can be expressed in specific values. These values are typically counted in whole numbers and cannot be broken down into smaller units. Dis...
In part 2 of the “how to model data” series, we answer the question “What are the different types of data models?” Take a look at various logical models, data model examples, their strengths and weaknesses, and pros and cons. Part 1 of this series covered the three steps of data...
The ultimate guide to data visualization. Learn how to present data visually using data visualization techniques and best practices. Lots of examples.
Nonparametric statistics refer to a statistical method in which the data are not assumed to come from prescribed models that are determined by a small number of parameters. Examples of such models include the normal distribution model and the linear regression model. ...
In this tutorial, you will learn about different data types we can use in Python with the help of examples.
Explore our guide to the largest family of visualizations: charts. Learn more about what they are, see examples of them, and discover the different types.
A TypedElement is a NamedElement that, in some way, represents particular values. Depending on the kind of TypedElement, the actual values that it represents may change over time. Examples of kinds of TypedElement include ValueSpecification, which directly specifies a collection of values (see Cl...
Examples of Data Modeling Consider this example of a small hotel chain to illustrate the role of data modeling and its importance to business decision-making. The hotel chain books rooms through three channels: it’s a call center, a website and many independent travel sites. The independent ...
