- Perception is a very important aspect of out life
- Most of out thoughts, ideas and expectations are based on our perceptions
- Perceptions are built using the knowledge and experience we gather in our day to day lives
- Perceptions can be different from one person to another
- Because, the knowledge and experience levels of each and every person is different from one to another
- Therefore, personal perceptional perceptions are subjective always
- But, it is always better if you can create your subjective perception somewhere near to the objective perception!!
- For an example, when a pole is rotating fast, we may see it as a complete round
- That is subjective perception
- But, when the rotation is stopped, we will see the real pole which is not round in shape
- That is objective perception
- The problem with subjective perception is, until you see the still pole, you won't belie that it is a pole
- You may take your decisions also based on your subjective perceptions
- But the real question you will face in this aspect is when you realize the fact that the objective perception is also subjective a different level!!
We use statistics as a tool to analyse the data we have With the use of statistics, we can convert a set of data we have at our hand to a more meaningful or more understandable form to facilitate our decisions When we analyse data of different groups, we will find that there are differences in the results between selected groups Media frequently tries to manipulate these data in order to mislead the public But, statistical difference does not always mean that there is a discrimination For an example, is we analyse the gender in prions, % of males are significantly higher compared to the females But this does not mean that prison system is discriminating against males
