ADVERTISEMENTS: Advantages and Limitations ‘Observation’ Method for Data Collection! On the other hand, you have the techniques of the data collector and their own unique observations that can alter the information in subtle ways. Observation is a technique that involves systematically selecting, watching, listening, reading, touching, and recording behavior and characteristics of living beings, objects, or phenomena. Nonetheless, manual data processing is also more prone to error, slower than its automated counterpart, and requires more time and expense on labor. Advantages of controlled observation method. Data Encryption: HTTP does not encrypt the data while transferring data between client and server. One must not confuse data science with data analytics because as data science is considered to be a box for tools and methods, data analysis is considered to be the chambers in the box. But it also has some disadvantages so for that reason, we are giving here some advantages and disadvantages of graphical representation of data.
