Question

You believe that there is a statistical relationship between both years of education and years of experience on a person's pay. You interview the first five people you meet on the street about the number of years of experience and education levels that these five people possess and their pay levels. You then conduct a regression using this data to see if there is a positive and significant relationship between these two independent variables and your dependent variable. You find a statistically insignificant relationship between both education and experience on pay. The p value for education is .74 and the p value for experience is .46. Based on the results of your study how confident would you be in asserting to our class that your study strongly suggests there is little relationship between a person's education and experience on their pay in the overall population. What would make you feel that way?

Explanation / Answer

We cannot be confident in asserting our class that our study strongly suggests there is little relationsip between a person' education and experience on their pay in the overall population.

REASONS ARE GIVEN BELOW:

(i) The sample size = n = 5 is extremely small for the decision we are taking: relationship between education and experience in the overall population

(ii) Type of sampling used is convenience sampling -just taken 5 people from street. The sample here should encompass the various strata of the society and suitable statistical techniques should be adopted o get a approprate representative sample.
