PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard will be able to understand and apply statistical techniques, including the organisation and presentation of data, probability theory and probability distributions, statistical inference techniques and correlation and regression analysis.
These learning outcomes form part of the Fundamental learning of the Bachelors Degree in Construction Management. This unit standard will contribute to the full development of a professional community of Construction Managers The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the construction environment 
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
