# SPSS homework solution

This solution is based on SPSS on lung cancer deaths as a result of either age or smoking. We have used both a histogram and bar graph to state the number of deaths.

## Analyzing the number of lung cancer deaths

Here we will indicate the variable data types, create frequency tables and come up with tables to show the level of deaths as a result of lung cancer.

The dataset you are using for this assignment has information on lung cancer deaths by age and smoking status (BST571_GradedAssignment1_Data). The data is already an SPSS dataset, so just double-click on the data, and it will open in SPSS.

Codebook for the data:

 Variable Description ID ID Variable agegrp Age Groups: 1 = 40 – 49 years, 2 = 50 – 59 years, 3 = 60 – 69 years, 4 = 70+ years smoking Smoking Status: 0 = Does Not Smoke, 1 = Smokes Cigars, Pipes, or Cigarettes pop Population – In Hundred Thousands deaths Number of Lung Cancer Deaths in a Year

1. Fill out the table below, indicating the variable type for each variable in the dataset (nominal, ordinal, or numerical):

 Variable Type agegrp Ordinal smoking Nominal pop Numerical deaths Numerical

2. Use SPSS to create frequency tables of agegrp and smoking. From the frequency tables, answer the following:

a. What percentage of patients were aged 60 – 69 years old?

Ans: 36.11%

b. What percentage of patients smoke?

Ans: 25%

c. How many patients are 70 years old or older?

Ans: 19.44%

3. Use SPSS to create descriptive tables of pop and deaths. From the descriptive tables, answer the following:

a. What are the mean and standard deviation for pop?

Ans: Mean = 1558.9444

SD = 1562.23217

b. What are the mean and standard deviation for deaths?

Ans: Mean = 253.6111

SD = 262.5975

c. What is the largest deaths value?

Ans: 1001

4. Create a histogram of deaths. Copy and paste the histogram below:

Ans: 5. Create a bar graph of agegrp. Copy and paste the bar graph below:

Ans:
