Quartile Deviation – The Semi-Spread of Data!
Quartile Deviation, also called Semi-Interquartile Range, tells us how spread out the middle 50% of values are in a dataset.
This means it focuses on the difference between the 75th percentile (Q3) and the 25th percentile (Q1), ignoring extreme values.
Great for understanding variability in psychological data when you want to avoid the effect of outliers!#statisticsforpsychology #psychologicalstatistics #education #psychologicalresearch #cuetpgstatistics #cuetstatistics #cuet #cuetpreparation #cuetpsychology #psychology #psychologyofeducation #pschology
