| $1.$ | In population survey all units are examined. Hence it requires more time. | $1.$ | In sample survey few units are examined. Hence it requires less time. |
| $2.$ | The cost of survey is more. | $2.$ | The cost of survey is less. |
| $3.$ | As more units are to be examined proper accuracy cannot be maintained. | $3.$ | Accuracy can be maintained as few units are to be examined. |
| $4.$ | Population study is not possible when the units are to be destroyed during the study. | $4.$ | Sample study can be used when the units are to be destroyed during the study. |
| $5.$ | AS more persons are to be employed in the work experts may not be available. | $5.$ | As few persons are to be employed, experts may be available. |
| $6.$ | As more units are tobe studied the work becomes tedious. | $6.$ | As few units are to be studied the work is relatively easy. |
| $7.$ | As all units are examined complete information is available. | $7.$ | Limited number of units are examined hence complete information is not available. |
