Data Transformation

It involves converting data from one format or structure to another to make it suitable for analysis. This includes converting data types, merging data sets, and reformatting data.

Data Filtering

Data filtering involves removing or excluding data that does not meet certain criteria. This can be used to remove outliers or data points that are not relevant to the analysis.

Data Imputation

Data imputation is the process of filling in missing values in the data. This can be done using statistical methods such as mean imputation, median imputation, or regression imputation.

Data Standardization

Data standardization involves ensuring that data is consistent and comparable across different sources or systems. This includes standardizing data formats, units of measurement, and data values.

Data Normalization

Data normalization involves scaling data to a common range or format. This can be used to make it easier to compare data across different variables or sources.

Stage 3: Data Exploration and Analysis

Data exploration or data science is the process of analyzing and summarizing data to identify patterns, trends, and relationships. Data analysis involves using statistical methods and models to derive insights and make predictions from the data.

Types of Data Analysis in Healthcare

There are several types of big data analysis commonly used in healthcare, including:

Descriptive Analysis

The descriptive analysis involves summarizing and describing data using measures such as mean, median, mode, and standard deviation. This type of analysis or descriptive analytics can help healthcare providers understand the characteristics of their data and identify patterns and trends.
