In research, the term systematic observation refers to a process to get data by which t<u>he researcher makes observations of the subjects of the study in an objective way</u>, not considering the researcher own prejudices by collecting data without biases from the researcher (which would come from the interpretation of the observations).
In this example Irina watches 10 babies once a month from birth to 2 years of age and writes down the sounds they make and the words they use. We can see that <u>she is observing the babies in an objective and close way and by writing down the sounds and words she is actually taking an objective measure of language development</u>. Therefore this would be an example of systematic observation.
