Collecting Data: Types and Techniques 📌📊📈

Good data collection is essential for accurate analysis. There are two types of data: quantitative and qualitative. Quantitative data is numerical data while qualitative data is descriptive data. Both are important and can be collected through surveys, interviews, online tools, and other methods.

To collect data, you need to determine the research question, choose the participants, and design the data collection method. You also need to ensure that the data is accurate, reliable, and valid. Data cleaning is also crucial to maintain data quality.

Preparing Data: Cleaning and Organizing 🛁🧺📋

Data preparation involves cleaning and organizing the data for analysis. This includes identifying and correcting errors, removing duplicates, and dealing with missing data.

Data cleaning is a time-consuming process but it’s important to ensure that the data used for analysis is accurate. Organizing the data involves labeling, categorizing, and formatting the data. This makes it easier to analyze and interpret the data.
