Reflection/ Statistical Journal


Statistics can help us manage how much we spend each month, how much we save or find out if your grades at school are improving or becoming worse. Statistics are rather useful for many working parents and all students of different schools. Examples of statistics being used in daily life might be at the stock market. Something like the picture shown below. The first time we learnt statistics during e-learning week shows us how a simple yet accurate graph could help the taxi companies. So without statistics, it would be very hard to take down information and sort them out correctly. However, even if is useful, if it is not done correctly.When the statistical reason involved is false or misapplied, this constitutes a statistical fallacy.The false statistics trap can be quite damaging to the quest for knowledge. For example, in medical science, correcting a falsehood may take decades and cost lives.Misuses can be easy to fall into. Professional scientists, even mathematicians and professional statisticians, can be fooled by even some simple methods, even if they are careful to check everything. Scientists have been known to fool themselves with statistics due to lack of knowledge of probability theory and lack of standardization of their tests.
