Thesis Keith Gale 2013proportionally of longer duration for £100k value of work than higher value projects.Causation is predominantly through the proportion of value of materials which arehigher in large value projects. Irrespective of value or project duration, the meanvalue of days starting late or finishing late are lower for framework projects whencompared to discrete projects included within this case study.7.7 Initial investigation of relationships between elements of raw data Type AFollowing initial empirical investigation of raw data type A, a series of scatterplotsare used to explore relationships between variables. This method allows visualindication of variables to be explored prior to conducting detailed analysis. Linearrelationships indicate a correlation of values whilst grouping of results along an axisshows strength of relationship between variables.Within scatterplot Figures 7.1 to 7.6, the label Project Group ‘1’ relates to resultsfrom 60 discreet pre-framework projects whereas label Project Group ‘2’ representsresults from 104 framework projects.Figure 7.1: Scatterplot graph exploring relationship between tender total andvariances in project durationConclusions from Figure 7.1:131
