LS3 - Statistical Infrequencies Flashcards
What Is Statistical Infrequency
When an individual possesses a less common characteristic than most of the population. - unusual behaviour which is seen as abnormal.
How Is Data Displayed
Using a Normal Distribution Curve.
Normal Distribution Curve- Left Skewed.
The tail is to the left, increases as you go right. This is negative skewness.
Normal Distribution Curve - Right Skewed.
The tail is to the right, increases as you go left. The is positive skewness.
Strengths Of Statistical Infrequency
Statistical infrequency can be a good thing (high IQ).
Based On Scientific Data (objective)
Weaknesses Of Statistical Infrequency
It involves labelling people as abnormal.
There is a subjective cut off point
Statistical Infrequency Can Be A Good Thing
- IQ of over 130 is statically infrequent but positive, desirable behaviour
- just because someone is statistically infrequent it doesn’t mean the person is abnormal and requires treatment.
Based On Scientific Data
- Judgements based on objective, scientific & unbiased data that help indicate abnormality and normality (gives a more accurate answer as to whether someone needs psychological help/assistance)
It Involves Labelling People As Abnormal
A person with low IQ of 70 might be labelled negatively by others = could have a negative effect on them (self confidence, self esteem) which leads to further problems
Subjective Cut Off Point
The cut off point of where normality ends and abnormality starts is subjective e.g. someone with an IQ of 69 is abnormal but someone with 70 ain’t
