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

Answer 1

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
