Question

NO DATA YET-NOT SURE ON HOW TO DO IT-STARTING WITH HOW DO I ATTAIN THE DATA? WHAT AREAS?

Develop your own questionnaire/survey to collect data on a two variables of interest. One variable of interest should be used to estimate a population mean (quantitative) and the other should be used to estimate a proportion (qualitative).

Topic 1: Population mean - For one of the variables of interest (Quantitative): ● Present the data you used  ○ Use appropriate displays (graphs) of the data. (box plot and histogram for quantitative) ■ Describe the data in terms of descriptive measures:
1. Centers ___ 2. Shape (1)____ 3. Variability (1)____ … in the CONTEXT of the problem.
Construct a 95% confidence interval for a population mean. (use technology) ○
Explain what the answer (confidence interval) means in the context of the problem.

Topic 2: Population proportion - For your second variable of interest (qualitative): ● Present the data you used ○ Use appropriate displays (graphs) of the data. (bar graph and pie chart) ○ Describe the data in appropriate terms of descriptive measures -
mean and standard deviation (standard error) of the proportion ■ [you will need to choose one answer to be the point of reference. For example, if you are going to survey on political parties then you could choose to find the mean and standard deviation of the proportion of the population that are republicans] in the CONTEXT of the problem.
● Construct a 99% confidence interval for a population proportion. (use technology)
○ Explain what the answer (confidence interval) means in the context of the problem

Answer 1

You can download data from UCI Machine Learning data repository, and it depends what type of data you want to work on. If it is finance then there is black friday data set - in this data set you will get both qualitative and quantitative variable, For Entertainment kind of data set you can go for Titanic or game of thrones from kaggle, both have decent number of data sets. then accordingly you can do analysis on R,

Step - 1

Download the data

Step - 2

Calculate the descriptive measure, For qualitative variable, Mode would be the central tendency, For quantitative variable mean, median would be better.

Step - 3

make plot by plot command in R

Step - 4

Make Confidence Interval
