Question
Numbeo is a crowd-sourced web site that gathers data on cities and countries around the world. Visitors to the site can add information on variables such as cost of living, traffic and crime. The data is searchable by city and country. For example, when we looked up Halifax, Canada, we discovered that a pair of jeans go for an average of $62.50. The range was $50 to $ 75. Add a summer dress from somewhere like Zara or H&M goes for an average of $48, with a range of $40 to $60. Numbeo also tells us that their Halifax data is based on contributions from 80 different people.Numbeo doesn’t tell us how many of the 80 contributors answered each of these questions. Why might the sample be even smaller than 80 for the average cost of summer dresses?
Explanation / Answer
The users in numbeo website are given questions to be answered and rated regarding their exenses. But they doesnt ake sure that a person will answer all the questions asked to him or her. In case of summer dresses, among the 80 people who must have rated in numeo, might not have mentioned the cost of summer dresses. All people who rated might not have visited the city in summer or they must not be sure of the cost and there is good chance that they must have skipped the question. Unless its made sure that each person have answered all the questions, the sample might be smaller than that of 80
