Methodology
The analysis greatly relied on a number of approaches to understand the rationale and need for
the study. First, frequencies were adopted to understand the state of the animal on kids and
gender (McCullagh 2019). Secondly, descriptive statistics was employed using measures of
central tendency and measures of dispersion using means, standard deviations, maximum,
minimum and standard error of the mean(Stajkovic et.al 2018, p.239). Thirdly, independent
sample t-tests were employed to check for the existence of differences between Fraction of pixels
located on the animal that cover the shed region of the animal and integer in the range [0,50],
derived from frac_shed, that is the number of 2% pixel blocks that are classed as shed in relation
to gender (Skillings 2018). Furthermore, it also tested for integer in the range [0,50], derived
from frac_shed, that is the number of 2% pixel blocks that are classed as unshed and gender.
Lastly, general linear models using the logistic regression model was developed to test for the
effect of the changes in fraction during winter on animal state(Chatfield 2018).

Results and analysis
Summary statistics
Table 1: Gender of the goats
Sex freq
1 1 9
2 2 49
On the gender of the goats, most of them were females at 84.5% (n=49) as compared to
their male counterparts at 15.5% (n=9). This indicates that the male goats were of less
dominance as compared to their female partners within the context of the study.
Table 2: State of the animal
Kid freq
1 0 46
2 1 12
On whether the animal was looking after a kid, most of the animals were actually not
looking for a kid at 81.0% (n=47). Only 19.0% (n=11) were looking after their respective kids,
hence varied levels of expectations in terms of care on the kids.

On the descriptive statistics, Fraction of pixels located on the animal that cover the shed
region of the animal proved an average of 0.421 with a corresponding standard deviation of
0.369 (M=0.421, SD=0.369), with a minimum of 0.000 and a maximum of 0.994. An integer in
the range [0,50], derived from frac_shed, that is the number of 2% pixel blocks that are classed
as shed showed ab average of 21.052 with a standard deviation of 18.517 (M=21.052,
