Inferential Survey
1. Design a simple survey with 4-5 questions that you will use to collect data.
Example: Age gender number of text messages sent per day hours of TV per day phone brand . You are free to choose whatever topic you want, just make sure it is easy enough that you will be able to collect data from 20-30 people quickly
2. Tabulate the data in an Excel sheet.
Example:
a. 35 male 24 texts 3 hours Iphone
b. 22 female 12 texts 0 hours Samsung
3. Perform some basic description of the data (summary statistics, charts); describe some findings.
Example
On average in my sample, people spend 2.1 hours watching TV. Male spend 2 hours while female spend 2.3 hours.
- Do you think you can generalize these findings about the entire American population? The worlds population? Why or why not?
5. Build a 95% confidence interval and a 99% confidence interval of one of the variables that you are measuring. Interpret and explain.
