Organizing the DataRaw data is unprocessed/unorganized source data, such as the data from an eyetracker which records the coordinates and movement of the eye every millisecond. Is the processed/summarized/categorized data such as the output of the mean position for a participant immediately after a stimulus was presented.is required in most. At the individual level, data needs to be processed because there may be several reasons why the data is an aberration.The raw data collected is often contains too much data to analyze it sensibly. This is especially so for research using computers as this may produce large amounts of data.
The data needs to be organized or manipulated using deconstruction analysis techniques. Data ManipulationIn involving, there are a number of possibilities why a given data set might need to be edited or processed. For example, the researcher finds an error in a question which makes it invalid. Participants may also have checked the wrong answer or may have simply misunderstood or skipped a question.It is also important to extract exactly the information that is needed from the overall experiment. For example, census data provides a wealth of geographic and demographic data, but a researcher might need only certain segments of the data from certain locations.Therefore raw data processing would be required in order to correctly extract the information required without errors.Raw data processing can be a time consuming task and it is not always easy to catch anomalies.
If you’d like to fix RAW partition without losing data, the last step is to recover data from RAW (MiniTool Power Data Recovery is a good choice for even green hands to recover lost files). The third way: make use of the powerful tool – WINHEX. Choose the RAW hard drive. Scan for lost partitions. Open found partitions.
Therefore simple checks should be run that are quite effective in eliminating the abnormalities.For example, a predefined range can be defined from most parameters that can be obtained in theory. Suppose a researcher is studying the amount of salts in a lake by averaging at different locations. At one particular location, it is possible that there is a sudden surge in salt levels, which is an anomaly and can happen if say, someone at a picnic dumped some salt there.However, this anomaly can be caught by determining a predefined range for the value of salt content in the lake that are usually available in literature.Such small tests often are very effective in raw data processing.
