Need to follow these steps:

  • Data requirements – this specifies the data that is necessary as input for the analysis and depends on the requirements.
  • Data collection – data collection is the process of gathering data of targeted variables found in the data requirements step.
  • Data processing – the collected data needs to be processed or organized for enhancing understandability.
  • Data cleaning – the processed data is not always error free. In this step, processed data is further looked in for errors, redundant values, incorrect or incomplete values etc and rectified.
  • Data analysis – once the data has been collected, processed and cleaned, it’s ready for analysis purpose. Various data analysis methods are applied to derive conclusions based on requirements.

  • Communication – analysed data is of no use if not communicated. In this step, conclusions derived are represented in a specific format and communicated to certain teams which will help those teams make better and promising decisions.Data requirements – this specifies the data that is necessary as input for the analysis and depends on the requirements.

Well explained @Maverick, In simple words the process of Data analysis consists of -

  • Data Loading - load data from various data sources
  • Data Cleaning - cleaning data i.e removing or filling null values, remove unnecessary data fields, rows, etc
  • Data Transformation - transform data to the same format, formatting of data.
  • Data Modelling - model or visualize data in various forms such as a table, charts, graphs, etc 
  • Data Analysis - perform data on the models made using in the previous step and gather insights, problems and solutions.
