The National Institutes of Health conducts ongoing surveys of US adults called the Health Information National Trends Survey (hereafter abbreviated HINTS). From the National Institutes of Health: "The HINTS data collection program was created to monitor changes in the rapidly evolving field of health communication. Survey researchers are using the data to understand how adults 18 years and older use different communication channels, including the Internet, to obtain vital health information for themselves and their loved ones...."

The most recent round of data collection occurred over the course of September 2013-November 2013 in HINTS 4 Cycle 3. Use a subset of the HINTS 4 Cycle 3 data to practice creating effective and informative graphical representations of data, which may include histograms and pie charts.

Please download the hintsdata.csv dataset. The variables you will be working with are as follows.

• Ageassume each person's age was rounded to the nearest year; for example, a person in the age range [19.5, 20.5) would have a reported age of 20, and a person in the range [20.5, 21.5) would have a reported age of 21, and so on.
• Genderthe gender of the respondent; categories include 1 = Male and 2 = Female.
• GeneralHealthhow the respondent rates their overall health; categories include 1 = Excellent, 2 = Very Good, 3 = Good, 4 = Fair, 5 = Poor.

A few important aspects of creating effective graphical displays of data include the following.

1. labeling your graphs with descriptive titles
2. ensuring that the x- and y-axes have appropriate labels
3. setting the axes to meaningful and/or useful scales

The graphs are expected to have these three characteristics.

Make a histogram of the variable Age with class intervals 10 years wide.

Describe the shape of the above histogram. The distribution is ---Select--- positively skewed nearly symmetric negatively skewed , centered near ---Select--- 45 55 65 , with ---Select--- little lots of variability. Make a pie chart of the variable GeneralHealth.

How the majority of people in the survey feel about their general state of health. The majority of people in the survey feel that their general state of health is ---Select--- excellent or very good good or very good fair or good fair or poor excellent or poor .You wish to determine if the age of the respondents who perceive themselves to be in good health differs from the age of the respondents who perceive themselves to be in poor health. Do this by creating two histograms. For the first histogram, plot the variable Age using only the data from respondents who rate their overall health as Excellent, Very Good, or Good. For the second histogram, plot the variable Age using only the data from respondents who rate their overall health as Fair or Poor. Label the histograms so that they have the same limits for the x-axis, y-axis, and class intervals, so that they can be directly compared.

Compare how men and women rate their general state of health using a comparative chart. Using your chart, briefly compare and contrast how men and women rate their general state of health.
