Answer 1

1. facial expression has a major effect on the generation of sweat. it can be depicted from the data that if a person has facial hair present then sweat generation is more than when facial hair are absent. scientifically it has been proven that hairy people have more activated sweat glands than non hairy people.
2. facial expression has a major effect on the sweat generated by people. it can be clearly seen from both the datas of with beard and without facial hair that when we smile the amount of sweat is 50% to that of cases where they have a scowled expression. the reason behind this might be that we need to put in more effort to show our attitude than to show our happiness.
3. although clothing type did not have much effect on the facial expression and also didnt change much by the presence or absence of the facial hair but a minor change can be seen in the smiling faces category by the formal dress up i.e. suit. it can be seen that the amount of scowled faces are more than that of smiling faces when a person wears suit because according to me a formal dressup increases your confidence and attitude which increases chances of having a scowled face.
4. there are 5 types of interactions that can be analysed by the given data. the interaction of facial hair with facial expression, the interaction of facial hair with clothing type, the interaction with facial hair on sweat, the interaction between facial expression and the clothing type as well as the interaction between facial hair and the sweat.
