Question
State the main difference between explicit weight and implicit weight.
| Points | Implicit Weight | Explicit Weight |
| $1.$ Meaning | The weights are included in the selection of items and they cannot be expressed numerically. This indirect method of assigning weight is called implicit weight. |
The weight to be assigned are determined in proportion to the importance of the item and can be expressed numerically. Such weight is called explicit weight. |
| $2.$ Calculation | Implicit weight is decided in the selection of commodities. Type of commodity is taken as weight. Like, in food items if $4$ types of rice is selected then their weight will be $4.$ |
Explicit weight is decided on the basis of use of commodity, sales, expenditure done, which is in proportion to the production of commodity. Like in food items, rice has double importance than wheat, then direct weight of rice $= 2$ and wheat $= 1.$ |
| $3.$ Numerical presentation | Indirect weight can not be shown in number. | Direct weight can be shown in number. |
| $4.$ Method | This is an indirect method to give weight. Therefore, there is no method to decide it. | This is direct method to give weight there are two methods of it : $(i)$ Total Expenditure Method and $(ii)$ Family Budget Method |
