If you have 2n scores, then
Q1 = (2n+1)/4
Q3 = 3*Q1
In both cases, depending on your level, you take the nearest integer to Q1 and Q3, or you interpolate. If you do not know what interpolate means then you are probably not yet at the necessary level!
and IQR = Q3 - Q1
the IQR is the third quartile minus the first quartile.
interquartile range or mean absolute deviation.
Interquartile range.

Range = maximum - minimum Interquartile range = Value of 75th percentile - value of 25th percentile. The 75th percentile is the value such that 25% of the observations are bigger and 75% are smaller.

what is the interquartile range of 16,17,19,22,23,25,27,36,38,40,40,45,46
the interquartile range is not sensitive to outliers.
the IQR is the third quartile minus the first quartile.
The interquartile range of a set of data is the difference between the upper quartile and lower quartile.
interquartile range or mean absolute deviation.
In general, you cannot. If the distribution can be assumed to be Gaussian [Normal] then you could use z-scores.
If presents you with the upper and lower quartile range, although you have to do calculations in order to find the interquartile range, so no, it does not,
interquartile range
The interquartile range is the upper quartile (75th percentile) minus (-) the lower percentile (75th percentile). The interquartile range uses 50% of the data. It is a measure of the "central tendency" just like the standard deviation. A small interquartile range means that most of the values lie close to each other.
Yes, it is.
how do you find the interquartile range of this data
