UM LEVEL 00 - Mod Pre-Tert, Foundation, Proficiency & DegreePlus

 
MQF LEVEL 4

 
ECTS CREDITS 2

 
DEPARTMENT Statistics and Operations Research

 
DESCRIPTION - Sampling Techniques
- Sampling Distributions of Means, Differences of Means, Proportions and Differences of Proportions
- Inference through confidence Intervals
- Inference through hypothesis testing
- Parametric tests using SPSS including the One-Sample T-test, Paired Samples T-test, Independent Samples T-test and One-Way ANOVA test
- Correlation analysis to assess relationships between continuous variables
- Assessing discrepancy between observed and expected frequency using Chi-Square test

Study-unit Aims:

- Familiarize with different sampling techniques (Random, Systematic, Stratified and Cluster sampling).
- Derive sampling distributions for sample means, proportions, difference of means and difference of proportions.
- Determine sample size and address uncertainty by providing margin of errors.
- Carry out statistical inference using confidence intervals and hypothesis testing.
- Apply statistical tests (One-Sample, Independent Samples, Paired Samples t-tests and One-Way ANOVA test) to compare means between population parameters.
- Apply statistical test (Pearson correlation test) to assess the relationship between two variables having a metric scale.
- Apply statistical test (Chi Squared test) to assess the association between two categorical variables.
- Assess discrepancy between observed and expected frequencies.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Understand the difference between sample statistics and population parameters.
- Familiarize with different sampling distributions of sample means, proportions, difference of means and difference of proportions.
- Familiarize with different ways of conducting statistical inference, mainly by computing confidence intervals and conducting hypothesis tests.
- Use statistical software (SPSS and EXCEL) to conduct hypothesis tests.

2. Skills:

By the end of the study-unit the student will be able to:
- Conduct statistical inference about a population parameter using sample statistics.
- Compute confidence interval for population means, proportions, difference of means, difference of proportions, variances and variance ratios.
- Use computer software, particularly SPSS and EXCEL, to conduct statistical test including the One Sample t-test, Independent Samples t-test, Paired Samples t-test, Chi Squared test, Pearson Correlation test and the One-Way ANOVA test.
