Statistics is the field of mathematical science that involves;
- Collection of data
- Analysis of data
- Reporting of information
- Presentation of data
Professional data management is an essential component of Statistical analysis. During the data collection process, we have to take care of two important error probabilities. The errors, can lead into inaccurate or faulty results and delayed results.
1: Errors that can occur, while we feed data into computers.
2: The digitization process should not take much time and it should be done quickly with the help of a professional team. otherwise the information can run out-dated and consequently lose its value to policy-makers.
(a)Normalization of the source data.
You can send us the collected data(this could be thousands of mailed questionnaires, figures on yearly accident rates for the fifty states etc etc.), may be through FTP, email or using any of the electronic mode of data transfer.
We will digitize the data and prepare the normalized data set for you. The data set can be delivered in spreadsheet format or migrated into a database or other.
The normalized data can be coded, as per the scope.
Joint efforts to:
Prepare data dictionary, or codebook
Prepare data matrix worksheets;
Prepare the instructions for data extraction and data analysis.
