WebApr 14, 2024 · Coyote (Canis latrans) depredation of sea turtle nests is a growing concern along the US East Coast and while several designs for predator exclusion cages (PECs) have been used, no one PEC is 100% effective. We investigated if PECs are a visual stimulus that lure coyotes to sea turtle nests. We used camera traps to evaluate coyote … Websigniﬁcant t-test by chance is 0.26. Therefore, for more than two samples, ANOVA must be used. This technique is based on the ratio between samples variance versus within samples variance using the omnibus Fisher F-test. If the F-test reached a signiﬁcant level, we can conclude that at least one sample mean is different from the others.

WebFeb 18, 2024 · Figure 2. Biological replicates derived from independent samples help capture random biological variation. For example, three biological replicates (A, B, and C) are collected from three independent mice. Each of these biological replicates was run in three technical replicates (A1, A2, A3; B1, B2, B3; C1, C2, C3) in one Western blot assay. WebSample Size vs. Replication. So I am having a hard time trying to grasp sample sizes and replication in the context of experiment design. The way I understand it, sample size refers to the entire scope of your study as taken from the population. And replication is just mere designating two or more runs with same treatment/factor.
