Here are the important aspects of Data Science you should know about.
· Data Collection- This is the process of gathering data that will be later useful for business decision-making and strategic planning. This practice can be conducted manually through surveys and focus groups or automatically through sensor-based tracking. There are three major kinds of data collection methodologies which are quantitative, qualitative and a combination of both. This practice collects quantitative data via surveys, polls, and experiments and Qualitative data via in-depth interviews, focus groups and observations.
· Data Cleaning- The next phase is data cleaning and transformation which is an essential part of the process. The Data is combined with multiple data sources and there are lots of chances that the data may be duplicated or mislabeled. In case the data is incorrect, outcomes and algorithms are not reliable. Therefore, cleaning the data information is extremely necessary and it helps in fixing or removing incorrectly formatted data within a dataset. Above all, it also helps in removing various kinds of errors such as missing values and duplicates.
· Data Transformation- After cleaning the data, it is necessary to change the data from one format into a new format. This step is necessary for ensuring that the data is useful for the analysis process. Along with it, the data transformation process includes extracting, transforming and loading the data for information. This practice consists of converting the data from one format to another and normalizing data. Furthermore, it also helps remove sensitive data and uses ETL tools to automate extracting data from its source.
· Statistical Analysis- After cleaning & transformation, the data goes through statistical analysis. This is an essential business skill that involves collecting, exploring, and presenting large amounts of data. The primary goal of this practice is to discover underlying patterns and trends. Furthermore, the Statistical analysis process is useful for comparing the results to past performance along with measuring the progress against goals and identifying any outliers.

· Data Visualization- The last but not the least practice is Data visualization which is useful for creating interactive visuals to quickly understand trends. Its primary aim is to derive meaningful insights from the information. Data Visualization provides a great way to share information with the team, stakeholders, and customers. Visuals make the data easy to share and understand. Some of the popular kinds of visuals are Graphs, Charts, Tables and Maps. Conducting Data Visualization allows businesses to take quick action in their operations.
