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? 450 243 227 248 248 291 278 228 241 209 265 234 209 257 252 255

Answer:Mean = 258.44

Median=248

Mode=209&248

Mid-range=329.5

Step-by-step explanation:

Mean=

sum of all numbers/number of occurrence

(450 + 243 + 227 + 248 + 248 + 291 + 278 + 228 + 241 + 209 + 265 + 234 + 209 + 257 + 252 + 255) / 16=258.44

Median = the middle number when arranged in accending or defending order=248

209 209 227 228 234 241 243 248 248 252 255 257 265 278 291 450

Since there 2 middle numbers (248 248) the median will be the mean of both which is (248+248) / 2

Mode = highest occuring number

(since there 2 numbers occurring the most) this is a Bi-mode = 209 and 248.

Mid range = (highest + lowest) / 2

(450+209) / 2

=329.5
