Thus, this study will attempt the application of dummy variables in regression model analysis in the presence of qualitative variables in a regression model. More specifically, the study developed a simple regression model that includes a dummy independent variable that models the cost price of repairing phones in a phone maintenance shop. The study utilized secondary data from the maintenance office and the model fitted was evaluated for adequacy where the p-value is less than 0.05, indicating the significance of both the model and the independent variable. More specifically the result revealed that the cost of repairing a mobile phone with screen-related issues is less in cost compared with panel repair issues. More interestingly, the application of the dummy variable pointed out that the cost will increase by about N10,000 when the repair is panel related....Preview Download Preview +Other Mathematics and Statistics project topics and materials you might be interested in»Statistical Quality Control of Premier Soap in Soap Manufacturing Industry ( A Case Study of PZ Cusson PLC Aba Abia State)»Statistical analysis of students’ height and weight (case study of federal polytechnic Nekede, Owerri, Imo state) »Statistical analysis of unemployment rate among age groups and geographical locations in Nigeria»Statistical analysis of the problems associated with skill acquisition in Nigeria (a case study of male tailors in Imo state)»Application of linear programming technique to profit maximization in the production of soap (a case study of Promotex industrial and chemical company limited, Nnewi, Anambra state) »Statistical analysis of foster care and adoption rate in Abia state (a case study of motherless babies home Ahiaeke, Umuahia)»Determination of nutritional status of children within the ages of four (4) to ten (10) years using their body mass index (BMI)»Time series analysis on marriage registration in Ilorin, Kwara state»Application of multiple queuing model in evaluating the efficiency of service in UBA bank»Statistical analysis on impact of parental hood on academic performance»Determinant of foreign direct investment in Nigeria and its effect on Nigerian economy: an empirical analysis»Econometrics analysis of gross national income on consumption expenditure of federal republic of Nigeria between (2011)»Statistical analysis of factors affecting crime in Imo state»Statistical study of the queuing pattern at the antinatal division of Federal Medical Center FMC Owerri Imo state»A statistical analysis of coal production in Nigeria - a case study of Nigeria coal corporation from 2000-2009
