Question

Did male residents seem to be more or less aggressive (by displaying dominance behaviors) towards intruder females compared to intruder males (base on T-test results)? Might there be an explanation for these observations? For this question only use the dominant scores (Dom) for the first round of observations (focal male 1A to 1H) for a total of eight pairs of data from Treatment 1 and Treatment 2.

The data represents 3 treatments (resident male vs intruder female), (resident male vs intruder male), injected resident male vs intruder male

In the data Sub means submissive behaviors.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
