What does pooled mean in statistics?
In statistics, “pooling” describes the practice of gathering together small sets of data that are assumed to have the same value of a characteristic (e.g., a mean) and using the combined larger set (the “pool”) to obtain a more precise estimate of that characteristic.
What does it mean to pool results?
Pooled testing is a screening approach that combines samples from some number of people into one test. The pooled sample is tested first. If negative, all members of the pool can be given a negative result immediately, saving the cost of testing each individual one at a time.
What does pooling mean in online selling?
Order pooling means combining several different customers’ orders on the same standard manufacturing panel. “Order pooling” or “pooling” is probably the most common name but the process is also called “order combination”, “panel sharing”, “multi-panels” …
What does pool mean in finance?
Pooling is the grouping together of assets, and related strategies for minimizing risk. For example: Asset-backed securities (ABS) is a security whose income payments are backed by a specified pool of underlying assets.
What is the formula for a pooled mean?
The Pooled Standard Deviation is a weighted average of standard deviations for two or more groups. Along with an updated degrees of freedom formula (df = n1 + n2 – 2), the idea is that you would be able to get a better model for the sampling distribution of the sample mean.
What is a pooled sample?
Pooling samples involves mixing several samples together in a “batch” or pooled sample, then testing the pooled sample with a diagnostic test. For example, four samples may be tested together, using only the resources needed for a single test.
What are pooled effect sizes?
The pooled mean effect size estimate (d+) is calculated using direct weights defined as the inverse of the variance of d for each study/stratum. An approximate confidence interval for d+ is given with a chi-square statistic and probability of this pooled effect size being equal to zero (Hedges and Olkin, 1985).
What does it mean when an exam is pooled?
Pooled testing means taking samples from multiple people, storing part of each sample individually, and combining the other part of each sample into batches, or pools, and then testing each pool.

When do we use pooled data in panel data?
Pooled data occur when we have a “time series of cross sections,” but the observations in each cross section do not necessarily refer to the same unit. o HGL is ambiguous about this and sometimes use pooled to refer to panel data Panel data refers to samples of the same cross-sectional units observed at multiple points in time.
How to calculate the pooled mean in statistics?
You calculate a pooled mean by adding up the mean times the sample size for each sample, and dividing this number by the sum of the sample sizes. ( M e a n 1 ∗ S a m p l e S i z e 1 + M e a n 2 ∗ S a m p l e S i z e 2 + M e a n 3 ∗ S a m p l e S i z e 3) / ( S a m p l e S i z e 1 + S a m p l e S i z e 2 + S a m p l e S i z e 3)
