Abstract
The feasibility of applying inferential statistics to the parameter estimate of manhours lost in the construction field in the Craftsman Questionnaire Survey is discussed. Currently, the Craftsman Questionnaire Survey only employs descriptive statistics to deal with masses of collected data. Inferential statistics have not yet been applied. Based on the theory of inferential statistics, the research can reliably infer the population properties from the data collected from a sample. To examine the feasibility of using inferential statistics to the Craftsman Questionnaire Survey, random and repeated sampling from past data was simulated. The results of the simulated samples are compared with the true results of the population, which were obtained from the past data. The comparisons empirically support that the inferential statistics can be applied to the Craftsman Questionnaire regarding the parameter estimate of lost manhours.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
