<h2>Text field</h2>
<p>The <strong>input type="text"</strong> defines a one-line text input field:</p>

<form action="/action_page.php">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname"><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname"><br><br>
  <input type="submit" value="Submit">
</form>

<p>Note that the form itself is not visible.</p>
<p>Also note that the default width of a text field is 20 characters.</p>

<h5>What is Data Science?</h5> 
<p>Data Science is about data gathering, analysis and decision-making.</p> 
<p>Data Science is about finding patterns in data, through analysis, and make future predictions.</p> 
<p>By using Data Science, companies are able to make:</p> 
<ul>
<li>• Better decisions (should we choose A or B)</li>
<li>• Predictive analysis (what will happen next?)</li>
<li>• Pattern discoveries (find pattern, or maybe hidden information in the data)</li>
</ul>
<h5>Where is Data Science Needed?</h5>
<p>Data Science is used in many industries in the world today, e.g. banking, consultancy, healthcare, and manufacturing.</p> 
<p>Examples of where Data Science is needed:</p>
<ul>
<li>• For route planning: To discover the best routes to ship</li>
<li>• To foresee delays for flight/ship/train etc. (through predictive analysis)</li>
<li>• To create promotional offers</li>
<li>• To find the best suited time to deliver goods</li>
<li>• To forecast the next years revenue for a company</li>
<li>• To analyze health benefit of training</li>
<li>• To predict who will win elections</li>
</ul>
<p>Data Science can be applied in nearly every part of a business where data is available. Examples are:</p> 
<ul>
<li>• Consumer goods</li>
<li>• Stock markets</li>
<li>• Industry</li>
<li>• Politics</li>
<li>• Logistic companies</li>
<li>• E-commerce</li>
</ul>
<h5>How Does a Data Scientist Work?</h5> 
<p>A Data Scientist requires expertise in several backgrounds:</p> 
<ul>
<li>• Machine Learning</li>
<li>• Statistics</li>
<li>• Programming (Python or R)</li>
<li>• Mathematics</li>
<li>• Databases </li>
</ul>
<p>A Data Scientist must find patterns within the data. Before he/she can find the patterns, he/she must organize the data in a standard format.</p> 
<p>Here is how a Data Scientist works:</p> 
<ul>
<li>• <b>Ask the right questions</b> - To understand the business problem.</li>
<li>• <b>Explore and collect data</b> - From database, web logs, customer feedback, etc.</li>
<li>• <b>Extract the data</b> - Transform the data to a standardized format.</li>
<li>• <b>Clean the data</b> - Remove erroneous values from the data.</li>
<li>• <b>Find and replace missing values</b> - Check for missing values and replace them with a suitable value (e.g. an average value).</li>
<li>• <b>Normalize data</b> - Scale the values in a practical range (e.g. 140 cm is smaller than 1,8 m. However, the number 140 is larger than 1,8. - so scaling is important).</li>
<li>• <b>Analyze data, find patterns and make future predictions.</b></li>
<li>• <b>Represent the result</b> - Present the result with useful insights in a way the "company" can understand.</li>
</ul>

Data Science is a combination of multiple disciplines that uses statistics, data analysis, and machine learning to analyze data and to extract knowledge and insights from it.

<h5>What are Algorithms?</h5> 
<p>An algorithm is a set of step-by-step instructions to solve a given problem or achieve a specific goal.

Pommes Frites Recipe
Pommes Frites Recipe
A cooking recipe written on a piece of paper is an example of an algorithm, where the goal is to make a certain dinner. The steps needed to make a specific dinner are described exactly.

When we talk about algorithms in Computer Science, the step-by-step instructions are written in a programming language, and instead of food ingredients, an algorithm uses data structures.

Algorithms are fundamental to computer programming as they provide step-by-step instructions for executing tasks. An efficient algorithm can help us to find the solution we are looking for, and to transform a slow program into a faster one.

By studying algorithms, developers can write better programs.
</p>

<h5>Algorithm examples:</h5> 
<ul><li>• Finding the fastest route in a GPS navigation system</li>
<li>• Navigating an airplane or a car (cruise control)</li>
<li>• Finding what users search for (search engine)</li>
<li>• Sorting, for example sorting movies by rating</li></ul>

The algorithms we will look at in this tutorial are designed to solve specific problems, and are often made to work on specific data structures. For example, the 'Bubble Sort' algorithm is designed to sort values, and is made to work on arrays.

<p>HTML is the standard markup language for creating Web pages.</p>
<h5>What is HTML?</h5> 
<ul>
<li>• HTML stands for Hyper Text Markup Language</li>
<li>• HTML is the standard markup language for creating Web pages</li>
<li>• HTML describes the structure of a Web page</li>
<li>• HTML consists of a series of elements</li>
<li>• HTML elements tell the browser how to display the content</li>
<li>• HTML elements label pieces of content such as "this is a heading", "this is a paragraph", "this is a link", etc.</li>
</ul>
<h5>A Simple HTML Document</h5> 
<pre>
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

</body>
</html>
</pre>
<h5>Example Explained</h5>
<ul>
<li><code>• The <!DOCTYPE html> declaration defines that this document is an HTML5 document</code> </li>
<li><code>• The <html>  element is the root element of an HTML page</code> </li>
<li><code>• The <head> element contains meta information about the HTML page</code> </li>
<li><code>• The <title> element specifies a title for the HTML page (which is shown in the browser's title bar or in the page's tab)</code> </li>
<li><code>• The <body> element defines the document's body, and is a container for all the visible contents, such as headings, paragraphs, images, hyperlinks, tables, lists, etc.</code> </li>
<li><code>• The <h1> element defines a large heading</code> </li>
<li><code>• The <p> element defines a paragraph</code> </li>
</ul>
<h5>What is an HTML Element?</h5> 
<p>An HTML element is defined by a start tag, some content, and an end tag:</p> 
<p><code><tagname> Content goes here... </tagname></code> </p> 
<p>The HTML <b>element</b> is everything from the start tag to the end tag:</p> 

<code><h1>My First Heading</h1></code> 
<code><p>My first paragraph.</p></code>
