It is used when researchers want to investigate the outliers from the "norm" when it comes to a particular trend. Intensity sampling The difference is that the cases selected are not as extreme. If you are interested in truancy .

Unusual or special cases may be particularly troublesome or especially enlightening, such as outstanding successes or notable failures. Homogeneous sampling. Typical case sampling. Focus groups have been used by researchers in many qualitative traditions and in qualitative descriptive research. Intensity SamplingChooses information-rich cases that manifest the phenomenon intensely, but not extremely, such as good students/poor students, above average/below average. Cases chosen for an intensity sample should be information-rich, manifesting the phenomenon intensely but not extremely; therefore capturing more typical cases compared with those at the extremes (Patton, 2002 . Intensity sampling fundamentally involves the same logic as extreme/deviant case sampling, but it has less emphasis on the extremes. An extreme case (or deviant case) can be thought of as an outlier an observation that takes on an extremely high or extremely low value.
