My employer is using copies of an excel worksheet to address student demographic data at each of our programs and to generate reports. For sundry reasons the employer insists on excel and not some proper database (even access is not acceptable only Excel). Data from a master database sheet/data entry sheet is being used to create report tables in other worksheets. When an employee adds a new entry/row to the master sheet I would like the new rows in the reports to be added automatically. I c...
Estimating population size worksheet
Hey guys! I’ve been on here a few times before, sharing my experience building a ~~35~~ 40 unit portfolio, with 36 of those located out-of-state. [Check out this AMA](https://www.reddit.com/r/realestateinvesting/comments/817z6d/ama_ive_built_a_portfolio_of_35_rental_units_and/) I did for the full story. I’ve had a bunch of people ask me specifically about how I analyze and choose out-of-state rental markets and what metrics I focus on, so this is a guide specifically for that. I hope that it ...
This is a fun and engaging activity for your students to practice how biologists estimate the population size of animals. Just print the worksheet and go. Includes background, the procedure, data table, and three follow-up questions. All you need is brown paper bags, and two different color beans.
A technique called sampling can be used to estimate population size. In this procedure, the organisms in a few small areas are counted and projected to the entire area. For instance, if a biologist counts 10 squirrels living in a 200-square foot area, she could predict that there are 100 squirrels living in a 2000 square foot area.

estimate of the actual population size (P). This method of estimation is called the Lincoln Index. P = (N 1 x N 2)/ R P = total size of population N 1 = size of first sample (all marked) N 2 = size of second sample (recapture: some will be marked, some won’t) R = number of marked individuals recaptured in second sample
