| Module Description: |
This module provides a treatment of descriptive statistics, probability distributions, and
regression and correlation. |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
Apply the methods of descriptive statistics to organise, summarise, present and analyse data. |
| LO2 |
Choose, use, and interpret summary statistics. |
| LO3 |
Calculate probabilities using the basic rules of probability and solve related applied problems. |
| LO4 |
Identify common probability distributions, in particular the normal
distribution, and calculate probabilities associated with them. |
| LO5 |
Determine and use the regression line for a set of bivariate data. |
| Pre-requisite learning |
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s). |
