Data Cleaning
The pre-survey dataset had 1,455 records, and the post-survey dataset had 414 records. On merging, we only had 292 records where the pre- and post- surveys were both done by the respondents.
We also conducted the following cleaning procedures:
- Irrelevant and Duplicate Fields: Removed from our dataset.
- Missing Data: Removed from our data set, null values were replaced with 0s to facilitate our analysis.
- Rectifying Discrepancies: Ensured data from pre- and post- survey were in comparable formats.
- Data Transformation: Transformed categorical data into numerical data for the Likert data analysis.
- Standardisation: Standardised name conventions for the variables in the merged data.
