Final answer:
A conventional index is based on a fixed scale, while a scaled index is adjusted to make it easier to work with.
Step-by-step explanation:
A conventional index is a measurement that is based on a fixed scale or standard. It does not take into account any changes or variations in the data being measured.
A scaled index, on the other hand, is a measurement that is adjusted or transformed to make it easier to work with. It uses a ratio or proportion to represent the data in a more meaningful way.
For example, let's say we have two sets of data: the number of visitors to a website in two different months. A conventional index would simply show the total number of visitors for each month. But a scaled index could be created by calculating the percentage change in visitors from one month to the next, giving a more meaningful comparison of the data.
