Data preparation

Why is data preparation important?

Data preparation is a key step in the process of analyzing and using information. Machine learning or business inference can be subject to errors and incorrect results Without properly prepared data, statistical analysis.

The importance of data preparation is due to several key reasons:

  • Reliability of results: correct and unambiguous data is the basis for reliable and relevant analysis results.
  • Error elimination: data preparation helps detect and fix errors in datasets, such as missing values, duplicates or invalid data, which affects the quality of analysis.
  • Consistency and standardisation: data processing allows its standardisation, which facilitates comparison, combining different data sources and ensuring consistency of information.
  • Time and resource optimisation: corrected and prepared data minimises time and effort required for analysis and improves the efficiency of business operations.

How do we do it?

Our data preparation services stand out for their advanced techniques and thorough approach to the process. Here is how we carry out the task:

  1. Data analysis: We start with a thorough analysis of the datasets to identify potential problems such as gaps, contamination and anomalies.
  2. Data cleansing: We use advanced tools to remove duplicates, fill in missing values, and correct errors to ensure consistent and clean data.
  3. Standardisation and normalisation: we bring different data sources into a consistent format, making it easier to combine information and ensure consistency.
  4. Data transformation: if required, we perform data transformation to adapt the data to specific analysis requirements, such as logarithmic transformations or scaling.
  5. Quality control: We carry out rigorous quality control to ensure that the data is ready for further analysis and use.

Our ‘Data Preparation’ service includes:

Data cleaning

Elimination of duplicates and errors, filling in missing values.

Standardisation and normalisation

Bringing different data formats into a consistent standardData transformation.

Data transformation

Data transformation, when analysis or the use of specific algorithms require it.

Data integration

Combining data from different sources into a consistent and complete set.

Quality check

Quality control of data to ensure that it is accurate and complete.

Statistical analysis

Preliminary data analysis to identify next steps and possible problems.

Our approach to data preparation is based on advanced techniques, attention to detail, and assurance of the highest quality data for our clients. This allows them to focus on analysing and using the data to make sound business decisions.
