DIY but size of population is 225, size of sample is 45.

To calculate the DIY with a sample size of 45 from a population of 225, first divide the population size by the sample size: 225 / 45 = 5. This is the sampling ratio. Next, take the reciprocal of the sampling ratio to find the DIY: 1 / 5 = 0.20 or 20%. Therefore, the DIY for this sample is 20%.
