If im given a frequency table, but instead of set scores, i am given classes, or a range of scores. So for example: 20-29 | 11 30-39 | 12 40-49 | 2 etc. If asked to find the median of the set of data, should i give the midpoint of the class containing the median score, or should i give the whole class. So in the example above, should i give 34.5, or 30-39? Thanks in advance, Dan.
