Thyroid Condition
   common among teens as well as adults
   marked either by underactive or overactive thyroid
    gland
   leads to Hypothyroidism or hyperthyroidism
   result of improper functioning of thyroid glands
    that fails to produce adequate insulin for the body
   characterized by low metabolism, weight gain or
    weight loss, fatigue, stress, muscular and joint
    pains.
Hypothesis
   I hypothesized that following factors have an impact on
    thyroid condition in human beings:
   Age and gender
   Body mass.
   Health regions
   Emotional attitude
   Physical activity level
   Regular diet
   Job hours
   Stress level

Age vs Thyroid Disorder
   strong positive linear correlation between age and
    male/female population having thyroid disorder
   cases of thyroid disorder increases with age.
   males and females might have different factors
    that affect there thyroid condition
   age is one such factor that is strongly correlated
    with both the male and female population
    suffering from thyroid disorder

Job Hours vs Thyroid
   standard deviation is 1.5 which shows percentage
    of population suffering from thyroid clusters
    around the mean in the range of 7.3
   The range of job hours is 3.9 with the mean value
    of 54.2
   job hours do not have a strong impact on thyroid
    condition
   increase in the job hours does not reflect an
    increase in the percentage of population suffering
    from thyroid disorder

Stress Level vs Thyroid
   The graph shows that higher the stress level the
    greater the percentage of population suffering
    from thyroid will be greater
   stress have an impact in worsening thyroid
    condition
   relationship is understandable as higher stress
    level can cause trouble in the secretion of
    hormones and in the functioning of the body
    glands.
   The average stress level is 20.6 with the median
    value of 20.5 in the range of 31

Diet vs Thyroid
   The graph shows a big difference between
    people who have thyroid condition and their
    regular diet.
   People who often did not eat the desired quality
    of food have the highest percentage of thyroid
    disorder.
   This is understandable as these people are most
    likely to lack sufficient nutrition needed for the
    proper functioning of the body

Diet vs Thyroid
   People in mature ages have less population who
    have thyroid due to the fact that they often did not
    eat the desired quality of food.
   Thus diet seem to have an impact on thyroid
    condition for those who are in young age.
   For the people who are older there might be other
    factors that play the dominant role in worsening
    thyroid condition.
   Thus poor diet can be considered as one factor
    why young people have thyroid.

Physical Activity vs Thyroid
   The graph shows strong positive linear correlation
    between the population suffering from thyroid disease
    with low physical activity level and age.
   The relationship is understandable as with age the level
    of physical activity is likely to fall and this can result in
    high percentage of population suffering from thyroid
    disorder.
   However physical activity          itself has a negative
    correlation with the percentage of population suffering
    from thyroid.
   The correlation is negative because increase in the level
    of physical activity will reduce the percentage of thyroid
    disorder cases.

Emotional Behaviour vs Thyroid

   The emotional behavior of a person is divided into five
    levels of sadness. Level 5 being the highest level of
    sadness has the highest percentage of thyroid disease.
   Thus from the graph conclusion can be made that the
    risk of thyroid disease increases with the level of
    sadness.
   The relationship between emotional behavior and thyroid
    shows strong positive linear correlation with the
    correlation coefficient of coefficient of 0.9506.
Emotional Behaviour vs Thyroid
   females are at a high risk of thyroid disorder than males
   thyroid condition has strong positive correlation with age, BMI and
    stress level and emotional behavior
   Increase in age, stress or BMI will result in an increase in the
    percentage of population suffering from thyroid disorder.
   Emotional behavior of a person indicates how the person feels for
    his life.
   People who have thyroid disorder tend to be more dissatisfied with
    life
   insufficient diet and physical activity have negative correlation with
    thyroid condition.
   Physical activity is one of the major indication of health
