Using Cross-Tabulation and Chi-Square Analysis to Validate Theories About the Causes of Building Defects Using Quantitative Likert Scale Data

Construction defects are prevalent in a construction project and worsen due to poor management and unstrict supervision. Thus, it is crucial to curb the problem from getting more significant. The objective of the study is to review various symptoms and causes of construction defects occurring in construction project. Compelling to the defects morphology aspect, X-tab with chi-square (χ2) helps to understand how “real” the relationship is between the variables meaningful and significant. Using a quantitative method approach with n = 86, ten drafted hypotheses on defect cause factors have been identified. Through Google Form of the Likert Scale survey results, the SPSS descriptive statistic analytical tabled out the dual-equation which denoted the hypotheses as a null (Ho) and should have not to be rejected. The conclusion is that controlling construction or building defects is the key and essential aspect of good construction.
