Question

Listed below are the playing times​ (in seconds) of songs that were popular at the time of this writing. Find the​ (a) mean,​ (b) median,​ (c) mode, and​ (d) midrange for the given sample data. Is there one time that is very different from the​ others? 444    240    227    248    248    296    281    230    243    213    261    236    213    263    258    255

Answer 1

a) Mean is the sum of data values divided by the number of data values

b) Arrange the data in ascending order as

213, 213, 227, 230, 236, 240, 243, 248, 248, 255, 258, 261, 263, 281, 296, 444

The middle value is the mean of 8th and 9th data value that is mean of 248, 248 which is 248

So Median is 248

c) The value which repeats more than others is the mode

Here there are two modes 213, 248

d) Here least value is 213 and highest value is 444,

Hence the Midrange is

e) The 444 second time is unusual as rest of the values are all between 213-296
