This task will go beyond the traditional idea to measure central tendency where a set of data is given and usually has been asked to compute mean. median or mode. The task will give you five questions and will ask to use analytical mind to provide solution. 1) A sequence consists of 7 terms arranged in descending order. The mean value of the sequence is 70. If 30 is added to each term, and then each term is divided by...
