Looking at the data set given, I have noticed a few aspects
of the study and data that may hinder or affect the credibility of the data.
One thing I noticed the study itself, the context of it to
be exact, it talks about the hydration with regards to weight and gender. This
alone doesn't give readers the information about the background and aspects of
the study, one example would be the type of activity that the participants will
be going through and such. Like any other study, a control group would be good
to have to compare between results and data.
Another component I noticed is the sample size between the
two genders, there is more females and males which in return may affect the
results of the study as if the data is used without trimming down equally may
result in biasness of the study towards females hence an inaccurate result.
Concentrating more on the table itself, it would be good to
have a title to tell readers on the content itself, unit of measurement would
do good in comparing of data, use of proper words instead abbreviations would
aid in the analysis of the data. As it is more multiple subjects, it would be
good to have a case id for each case so that the researcher can identify
certain cases.Looking at the data and quick analysis done by using line graphs, I noticed a trend between the differences in the color of the urine with regards to the weight. Its seems that for the males, as the time goes from the beginning and end of the activity there is a corresponding trend between the weight lost in coherence with the urine color, for instance, male subject 5 has a difference of urine color of -4 which in turns reflect a lost of 3.35, this surely shows the relationship between these two variables.
