What is the difference between observation and Inferrence?
An alternate answer.
The standard deviation of a single observation is not defined. With a single observation, the mean of the observation(s) would be the same as the value of the observation itself. By definition, therefore, the deviation (difference between observation and mean) would always be zero. Rather a pointless exercise!
A quantitative [think 'quantity'] observation is an observation that you can relate specific numbers to. For example, a quantitative observation might be "It rained 1.5 inches yesterday." A qualitative [think 'quality'] observation is an observation that does not include specific numbers, such as "It rained a lot yesterday" or "It rained more yesterday than today."
A qualitative observation has to do with things you can't count, "The fish has black scales" is a qualitative observation. A quantitative observation has to do with things you can count, "The fish has 125 scales" is a quantitative observation. You can combine these two, an example would be "The fish has 125 black scales."
The difference is that naturalistic observation is a research method, this technique involves observing subjects in their natural environment. It is usual used in situations where conducing a lab research is unrealistic, cost prohibitive, or would unduly affect the subject's behaviour. And controlled observations are studies that the situations are planned by the researcher, this type of observation may be carried out in a laboratory type situation and because variables are manipulated and said to…
The words, observation and survey, each have several different meanings, but they also have a meaning that is similar. One definition of observation and survey is the act of observing, looking or seeing. Another definition for observation is the act of noticing something. Another definition for survey is the act of making an inspection.
