Statistical methods and analysis can be challenging but it has the potential to greatly enhance your research practice. Whether you are brand new to statistics or a more experienced statistician, it is worth taking the time to reflect on those areas of statistics in which you feel more, or less, confident. The aim of this tool is to help you to identify your professional development needs and to encourage reflection on the types of scenarios this programme will equip you to approach with confidence.

Though some of the following scenarios may not map directly onto your area of research, you should view them as representing similar situations to those you may expect to encounter in your own subject area.

The tool below is designed to help you assess your level of confidence and understanding of the key topics covered in this course. You will be presented with a series of scenarios and statements. Read the scenarios and reflect on how confident you would feel in the situation, then use the rating scale to indicate your level of agreement (ranging from '1. Strongly disagree' to '5. Strongly agree').

Select 'View feedback' to submit your response and reveal some feedback, then proceed to the next scenario. When you have submitted a response to all of the statements, you will receive a personalised summary of recommended modules to prioritise.

It's great to see that you feel confident in developing a research plan with a strong statistical foundation. However, it's always helpful to review your plan with a critical eye. Have you selected the most appropriate statistical tests and methods for your data? Are you considering potential limitations or alternative statistical approaches?

Review your list of research planning steps, paying attention to any statistical choices that could further enhance your research outcomes. Discussing your plan with a senior colleague or supervisor can also help to refine and strengthen your approach.

For coverage of inferential statistics, you are recommended to study the following four modules: Evidence-based statistical inference; False positives? False negatives? The need for reproducibility of results; Categorical predictors with analysis of variance (ANOVA); Explaining the world of variation through linear modelling. These modules range from hypothesis testing to implementation in the context of analysis of variance and linear regression.

You have obtained data for your research project and are about to embark on exploratory data analysis. You are intending to summarise the data graphically using data visualisation to investigate variables individually and together.

Please indicate your level of agreement with the following statement:

“I feel confident in choosing the correct visualisation type for plotting a single variable and for plotting multiple variables.”

1.

Strongly disagree

It may be helpful to review the core principles of data visualisation covered in Storytelling with data visualisation and exploratory analysis with descriptive statistics. In particular, bar charts, histograms and density plots are discussed in terms of their suitability for plotting single variables, while boxplots and different types of scatter plots are presented as being effective ways of visualising relationships between variables. The module also looks at descriptive statistics, showing how variables can be summarised numerically.

Exploratory data analysis is an essential first step in an empirical analysis allowing you to get a "feel" for the data, while plotting multiple variables is an effective way of identifying interesting relationships which could be researched in greater depth.

Modules Categorical predictors with analysis of variance (ANOVA) and Explaining the world of variation through linear modelling are excellent for subsequently more formally investigating the statistical significance of any suggested relationships. Categorical predictors with analysis of variance (ANOVA) considers how categorical variables can explain variation in quantitative variables, while Explaining the world of variation through linear modelling uses quantitative variables as the "predictor" variables.

When conducting hypothesis tests, it is essential to understand the difference between Type I and Type II errors, as they affect the validity of your conclusions. A Type I error involves rejecting a true null hypothesis, while a Type II error involves failing to reject a false null hypothesis.

Please indicate your level of agreement with the following statement:

“I feel confident in distinguishing between Type I and Type II errors and understanding their implications in hypothesis testing.”

1.

Strongly disagree

If you selected one of these options, it suggests that you might need more clarity on the distinctions between Type I and Type II errors and their significance in statistical testing. Focus on Evidence-based statistical inference, which provides a detailed explanation of both error types and their role in hypothesis testing. Understanding these errors is essential for interpreting the results of your tests correctly. A Type I error, for instance, means that you've rejected a null hypothesis when it is actually true (false positive), while a Type II error involves failing to reject a null hypothesis when it is false (false negative). Grasping the trade-offs between these errors is key to ensuring the validity of your analysis.

In addition to learning how to identify these errors, False positives? False negatives? The need for reproducibility of results covers the factors that influence their occurrence, such as sample size, significance level, and power of the test.

In hypothesis testing, the p-value plays a key role in determining whether a result is statistically significant. The p-value represents the probability of observing your data, or something more extreme, assuming the null hypothesis is true.

Please indicate your level of agreement with the following statement:

“I feel confident in interpreting p-values and understanding how they determine statistical significance in hypothesis testing..”

Strongly disagree

If you selected one of these options, it indicates that you may need to deepen your understanding of p-values and their role in determining statistical significance. Focus on Evidence-based statistical inference, which explains the fundamentals of p-values and what they represent in the context of hypothesis testing. A p-value helps you determine whether the observed effect in your data is statistically significant or likely due to chance. Typically, if the p-value is below a certain threshold (for example, 0.05), the result is considered statistically significant, meaning you reject the null hypothesis. However, it is essential to understand that statistical significance does not necessarily imply practical significance, and small p-values may still arise by chance.
