What does pooled data set means?

What is a difference between a pooled variance and a combined variance?
Pooled variance is a method for estimating variance given several different samples taken in different circumstances where the mean may vary between samples but the true variance (equivalently, precision) is assumed to remain the same. A combined variance is a method for estimating variance from several samples, given the size, mean and standard deviation of each. Mathematically, a combined variance is equal to the calculated variance of the set of the data from all samples. See links.

What is a 'pooled SEM' for an ANOVA and how can it be calculated?
A pooled standard error of the mean (SEM) in the context of ANOVA refers to a combined estimate of variability across different groups, allowing for a more accurate assessment of differences between group means. It is calculated by taking the square root of the pooled variance, which is the weighted average of the variances of the individual groups, using the formula: [ \text{Pooled Variance} = \frac{\sum{(n_i - 1) s_i^2}}{\sum{(n_i - 1)}} ] where (n_i) is the sample size and (s_i^2) is the variance for each group. The pooled SEM is then derived by dividing the pooled standard deviation by the square root of the total sample size across all groups.

Is carbon pooled in phytoplankton and is carbon pooled in animal too?
Kingdoms of vegetals and animals are dominated by the carbon chemistry.
What is the difference between integrated and pooled?
Integrated typically refers to a system or approach where various components or elements work together cohesively, often sharing data and functionality to enhance efficiency and effectiveness. Pooled, on the other hand, suggests a gathering or accumulation of resources or data from multiple sources, often for collective use or analysis. While integration emphasizes synergy and collaboration, pooling focuses on the aggregation of resources or assets.

What are the key differences between pooled funds and mutual funds?
Pooled funds are investments where multiple investors contribute money into a single fund, while mutual funds are a type of pooled fund that is managed by a professional investment company. Pooled funds can include various types of investments, while mutual funds typically focus on stocks, bonds, or a combination of both. Additionally, mutual funds are regulated by the Securities and Exchange Commission (SEC), while other pooled funds may not be subject to the same regulations.
