If the median score is 1 out of 120 for 4164 participants
The histogram of the data will be right skewed
To decide the outliers with definitions related to box plot, the definition is
a data point is an outlier if it is more than 1.5 * IQR1 above the third quartile or below the first quartile.
Said differently, low outliers are below Q1−1.5*IQR
and high outliers are above Q3+1.5*IQR
To understand the outliers we need
- Q1 - Quartile 1 (25th percentile of the data)
- Q3 - Quartile 3 (75th percentile of the data)
IQR will be calculated as Q3 - Q1
