Psychology without statistics is nothing, whereas statistics has always been misunderstood as a form of maths which it is no longer the case. Statistics is an very important key to the world of science. Other than psychology, many other science based subjects would need statistics as their backbone based information, for example medicine, chemistry and space science, these subjects would require an in-depth data in order to pursuit further discoveries or experiments, therefore, by having a precise, reliable, representable statistical data will benefit science based subjects.
In order to fully understand the result of a psychological research or even normal research, the knowledge or background of statistics is very essential. For instances, the famous procedure, The Strange Situation* which looked into attachment between infants and caregivers which found a big portion(~70%) of the infants were securely attached to their mum(or caregiver), and ~30% of infants were insecurely attached(contains 2 types: resistant and avoidant). However, it was done with 100 American middle-class families. To entirely comprehend it, other than look at the % it produced, the sample size and the background of data would need to take into account, therefore the result might be different or could not represent the general population if any of the factors such as the cultural, economical status and ethic group have changed.
In the world of business, many commercial advertising would often “cheat” with their data in order to attract people to buy and try their products and unsurprisingly it is very often to see on billboards for something like 75% users would recommend this to a friend. However there would also be a small print at the bottom of the advert or at the end of the advert suggesting that there were only 60 participants took part in the sample survey. If the viewers did not pay any attention to these kind of adverts, they might consume the product based on the “statistic” provided by the advert. As there were only 60 participants who took on the survey, 75% of 60 participants is 45 participants, and comparing this statistics to the real world, it is really insignificant, hence the results obtained is not representable, reliable thus it is not a valid result.
In conclusion, being confident at statistics as a psychology students or as an individual, would certainly be an advantage, and researches would benefit from having a reliable, representable, statistical data by drawing out the conclusion clearly and confidently and thus would be supportive to the research.
