Aims & Objectives:

This unit of study aims to:
• develop students’ capacity to carry out independent statistical investigations.
• develop an awareness of the assumptions and limitations involved with the generalisation of the results of such investigations.
• provide the skills to communicate effectively the findings of an investigation in the written form via a report.
After successfully completing this unit, you should be able to demonstrate:
• an understanding of how to pose a question including making a clear statement of the objectives of a study and specifying/classifying according to the level of measurement the variables of interest in a study.
• knowledge of how to collect data including the ability to identify the research design (observational study/experimental) used in a study and how to obtain a suitable sample.
• ability to analyse data using IBM SPSS statistics including: 
         * describing the distribution of a single categorical variable using frequency tables, and generalising to the population using hypothesis tests and/or confidence intervals for a single proportion. 
         * describing the distribution of a single metric variable using histograms, stemplots, boxplots, summary statistics and generalising to the population using hypothesis tests (normal and t) and/or confidence intervals for a single mean. 
         * describing the relationship between two metric variables using scatterplots, correlation coefficients (Pearson’s r), the coefficient of determination (r2), and a line of best fit and,generalising to the population using hypothesis tests for Pearson's r. An understanding of correlation and causality. 
         • describing the relationship between two categorical variables using crosstabulation (tables), percentaged and generalising to the population using the chi-squared test. 
         • describing the relationship between a metric and a categorical variable using parallel boxplots, back-to-back stemplots, sets of summary statistics and generalising to the population using the t-test for two means for both related and independent groups.
• An ability to Interprete the results: 
         • use the outcomes of data analysis to answer a question. 
         • suggest directions for further investigations as the results of a study. 
         • communicate the results via written reports, using correct statistical notation including using Microsoft Equation Editor.
