Understand the Basics of Data Analysis.

To begin your data handling journey, it’s important to understand the basics of data analysis. This include becoming familiar with concepts such as how to read and interpret data from various sources, joint and separate frequency distribution tables, mean, median, mode and range. By understanding these core statistical tools, you will be able to effectively analyze datasets and draw meaningful conclusions.

Differentiate Between Primary and Secondary Sources of Data.
Before you dive into data analysis, it’s important to be familiar with the different types of sources of data. Primary sources are those that come from first-hand accounts and direct records, such as questionnaires and surveys which collect quantitative or qualitative data. Secondary sources, on the other hand, are often those previously compiled by other authors or government agencies, such as reports published in newspapers or online databases. Understanding these varying types of data and where they come from will help you more accurately interpret the information you encounter.

Develop Skills in Collecting, Storing and Representing Data.
Data can be collected through interviews, surveys and experiments. Experiments provide the most reliable type of evidence to prove any hypothesis as they are conducted in controlled conditions. After data has been collected, it is stored in a systematic manner so that it can be used effectively. Representations of data include tables, charts and diagrams which make the data easier to understand. Being able to accurately collect and represent data with these tools will help you get the most out of your data handling class.

Learn to Analyse and interpret data to draw meaningful conclusions

Once data is gathered and organized, it's important to be able to analyse it and interpret its meaning. Analysing data can involve establishing relationships between variables or calculating averages, medians and other numerical values. Overall, when correctly interpreted and analysed, data not only gives an insight into a given situation but also helps you identify trends, make decisions, draw valid conclusions and solve problems effectively.

Know About Data Security and Etiquette Before Working with Personal Data.
Data handling involves working with sensitive information, whether it is personal or not. It is important to know how to handle data securely, lawfully and properly. Ensure that you understand the data protection legislation relevant to your country and the ethical principles regarding data handling. When working with personal datasets, take extra care not to expose it publicly or make it accessible without permission. Additionally, never share confidential information without authorisation and adhere strictly to the rules of confidentiality concerning personal data.
