Do these data have a mode? Explain
Homework Answers
putting above data in ascending order:
| s. no | x |
| 1 | 2720 |
| 2 | 3726 |
| 3 | 5346 |
| 4 | 7155 |
| 5 | 13057 |
| 6 | 16022 |
| 7 | 19476 |
| 8 | 21423 |
| 9 | 32580 |
| 10 | 37037 |
mean =total/n= 158542/10=15854.2
median =middle value =(13057+16022)/2=14539.5
there is no mode as all values appears only once; therefore there is no value is most frequent,
