    Comparing temperature-during-stress with temperature-during-stand

    Hello, I've conducted an stress experiment in chickens. I want to compare the rate-of-change (ROC) in temperature right after a stressor was introduced, with the rate-of-change in temperature during a normal standing period of the chicken. I have 9 chickens, so 9 observations of the...

    Paired t-test using only 1 'after' measurement

    Okay, thank you very much! So the steps you suggest is: - Downsample my whole dataset so that a lower sampling frequency is used - Split my data set in 2: prior to stress and post-stress - Calculate limits in the I/MR chart based on the prior-stress datasubset. - Add in the post-stress datasubset

    Paired t-test using only 1 'after' measurement

    For example, I have extracted temperature data 2 minutes before and 2 minutes after a short, sound pulse/stressor, was introduced in the chicken. This temperature vector is 7001 datapoints long, since the temperature sensor had a sampling rate of 25 Hz. In attachment, you can find a figure of a...

    Paired t-test using only 1 'after' measurement

    Hello, I took a look at the individual control charts. It does seem appealing to use! However... I'm struggling how to create the chart. I only have the temperature data of the 5 specific behaviors and the temperature data of the stressor-periods. So... How should I create the plot? Thanks a...

    Paired t-test using only 1 'after' measurement

    Hello, I have conducted an experiment in chickens. A leg temperature sensor was mounted on the chicken's leg for 7 days. On the 7th day, a stressor (e.g loud noise) was introduced. We expected that the leg temperature would change immediately after stressor introduction, and this is also what...

    What do you mean by residuals?

    Compare continuous temperature data across 4 different groups

    Hello, We've got an experiment which involved temperature monitoring of 12 chickens. Sampling rate of the temperature sensor was 25Hz. Chickens were divided into 4 groups, 3 chickens per group. We tested 4 stressors A,B,C,D in each group on 4 consecutive testing days, but always in a different...
