compute the mean range and standard deviation for th edata
compute the mean , range and standard deviation for th edata items in each of the samples. explain how the sets are similar or different
sample a: 19,27,35, 43,51,59,67 sample b: 19,23,27,43,59,63,67 sample C.19,19,19,43,67,67,67
Solution
Sol)
Since all means and Ranges for three samples are same but standard deviation is different.
| A | B | C | |
| 19 | 19 | 19 | |
| 27 | 23 | 19 | |
| 35 | 27 | 19 | |
| 43 | 43 | 43 | |
| 51 | 59 | 67 | |
| 59 | 63 | 67 | |
| 67 | 67 | 67 | |
| Mean= | 43 | 43 | 43 |
| large= | 67 | 67 | 67 |
| small= | 19 | 19 | 19 |
| Range= | 48 | 48 | 48 |
| Standard deviation | 17.28198 | 20.26491 | 24 |
