| UNIT STANDARD RANGE |
| This unit standard includes the requirement to: Critique the selection of samples in terms of size and representativeness. Identify features of distributions: symmetry and asymmetry, clusters and gaps, and possible outliers in data and consider their effects on the interpretation of the data. Critique the use of data from samples to estimate population statistics. Apply an understanding of random phenomena to critique and interpret real life and work related situations. Critique arguments based on probability in terms of an understanding of random behaviour and the law of large numbers (e.g. lottery `hot` numbers). Demonstrate understanding of and determine probabilities for independent, disjoint and complementary events. Judge or critique probability values. Further range statements are provided for specific outcomes and assessment criteria as needed. |
