Looking at the cross tabulation, it shows that 12% of patients in anxiety level group have slept normally. The patients with no anxiety levels had 4% and the patients with mild anxiety had 8% and there were no moderate and severe anxiety levels

The probability that a patient will have moderate anxiety levels are 7/25. Having 25 female patients who are and are not sleep normally.

Looking at the clustered barchart, i can see that there are approximately 12.5 patients with mild anxiety levels who don't sleep normally, 7.5 patients with moderate anxiety levels, 1.5 with none or severe anxiety levels. On the left hand side, 2 patients are sleeping normally who have mild anxiety levels and 1.5 have no anxiety levels.

The table shows that the average of 40 moderately anxious patients would not sleep normally.

Looking at the table and clustered bar chart, the patients do not sleep normally as age increases and anxiety increases. This is shown that the average is 0 with moderate and severe anxiety levels meaning that patients sleep normally, however when age increases the moderate and severe anxiety levels are 40 and 43.

This clustered bar graph shows that the percentages of the patients who fall in different categories of anxiety levels.

According to the table, the negative mean weight shows the patients lost weight and the positive mean shows the patients gained weight.

The clustered bar chart, the patients who have lost weight, have no anxiety levels are the ones who have no or mild depression levels However the patients who have gained weight and have mild, moderate and severe anxiety levels, show that they have mild and moderate depression levels.

The clustered bar graph shows that as the anxiety level increases, at the same time the depression level increase as well. the patients who have no anxiety levels have none or mild depression levels. The severe anxious patients have moderately depression level.

The patients who do have suicidal thoughts have a median of roughly 90 whereas the patients who don't have suicidal thoughts have a median of roughly 92. The range is wider (82-97) for the patients who do have suicidal thoughts, whereas the range is less wider (87-96). Both box plots are positive but the box plot showing the patients with no suicidal thoughts seem to be more positvely skewed than the box plot showing patients with suicidal thoughts. There is an outlier on the box plot showing the patients with no suicidal thoughts.

The scatter graphs shows a positive weak correlation where as the overall psychiatric symptoms increase, the weight change in kgs increase. There are few outliers due to higher or lower psychiatric symptoms.
