It seems like you're asking about different types of Frequency Distribution Tables (FDT). Here's a brief explanation of each:

1. Cumulative FDT: This type of table displays the cumulative frequency of a set of data. In other words, it shows the total number of observations that fall below the upper limit of a particular class or group.

2. Relative FDT: This table shows the relative frequency of each group. The relative frequency is calculated by dividing the frequency of each group by the total number of observations.

3. Grouped FDT: This table is used when the data set is large. The data is divided into groups or classes and the frequency of each group is recorded.

Each of these tables serves a different purpose and can be used based on the requirements of your data analysis.
