These are the top reasons why statistics assignments seem challenging:

1. Struggle to select the right test: first, students have to decide between models like t-tests, ANOVA, regression, or chi-square. It depends on the research question and data type.

2. Data cleaning and preparation: missing values, duplicate entries, or unformatted variables in the datasets must be cleaned.

3. Software and programming issues: Tests require verifying specific conditions like normality, independence, or variance homogeneity.

4. Abstract concept: concepts like variance, p-values, and probability distributions are complex to visualise as compared to physical concepts.

However, if you face any challenge, then seek help from a statistics assignment helper.
