’ ’ ’ If quantile is 20% of data,how is 50th percentile is equivalent to Q2.? ’ ’ ’

Hi @leel438,

Can you please describe your question a bit more, and what’s the source of this question?

Q2 here might be referring to `quartile`

(not `quintile`

or `quantile`

)

`quantile`

, `quartile`

and `quintile`

are * similar sounding but different* terms.

I am going through w7 descriptive statistics- measures of spread .

I am confuesed with I Q R concept. Could you kindly provide info

If you know what Q1, Q2, Q3 and Q4 means. Then you can calculate all four Quartiles.

The Inter Quartiles Range is a measure of where the “Middle Fifty” is in a given data set. It signifies the measure of where the bulk of values lie.

Or in percentile language, it shows the range of Data that is greater than 25% of values in a data set and less than 75% of values in a data set.
