  1. Using 2 Proportion Z Test to validate the difference between amounts allocated between two periods

    Thanks a lot Mayank for the response. As we are currently in October 2024, we have complete data only till September 2024. Hence, in order to carry out a same period comparison between 2023 and 2024, we went for Jan to September in 2023 as well.

  2. Using 2 Proportion Z Test to validate the difference between amounts allocated between two periods

    Jaya Sivasankar posted a topic in You ask application questions here.
    I have 2 sets of data. The first data set consists of the total amount of money that was received in 2023 (between January 2023 and September 2023) and out of this, how much was allocated to the right account. The second set of data is the total amount that was received between January 2024 and September 2024 and out of this, how much was allocated. While comparing 2023 and 2024 allocations, the proportion of money allocated in 2024 is higher than 2023. The formula used for calculating proportion is, Proportion = Amount Allocated / Total Amount Received Is it right to use 2 Proportion Z test to validate that the difference in proportion between 2023 and 2024 is statistically significant?
