What is an example of a rank function
RANK gives duplicate numbers the same rank. However, the presence of duplicate numbers affects the ranks of subsequent numbers. For example, in a list of integers sorted in ascending order, if the number 10 appears twice and has a rank of 5, then 11 would have a rank of 7 (no number would have a rank of 6).

When to use rank and Row_number
ROW_NUMBER and RANK are similar. ROW_NUMBER numbers all rows sequentially (for example 1, 2, 3, 4, 5). RANK provides the same numeric value for ties (for example 1, 2, 2, 4, 5). ROW_NUMBER is a temporary value calculated when the query is run.

They provide a way to compare institutions, benchmark performance, identify areas for improvement, and promote a culture of excellence. The world needs university rankings to help ensure that higher education is accessible, affordable, and of the highest quality.
How do you measure rank
How to calculate percentile rankFind the percentile of your data set. Calculate the percentile of the data set you're measuring so you can calculate the percentile rank.Find the number of items in the data set.Multiply the sum of the number of items and one by 100.Divide the percentile by the product of 100 and n+1.
Why do we use rank in Excel
Excel RANK formula is used to give us the rank of a given dataset of numbers based on the data set, or we can say by comparing the other numbers in the data set. The RANK function was a built-in function for Excel 2007 and earlier versions.
When to use rank and Dense_rank
RANK : The rank function is a SQL function specifically used to calculate each row's ranking depending on the defined attributes and clauses. It skips a rank who has the same record values. DENSE_RANK : The dense_rank function is a SQL function which assigns rank number to each row.

When to use ROW_NUMBER rank and Dense_rank
In the case of the tie, ROW_NUMBER() will give unique row numbers, the rank will give the same rank, but the next different rank will not be in sequence, there will be a gap. In the case of dense_rank, both rows in the tie will have the same rank and there will be no gap. The next different rank will be in sequence.
