The process least likely to be part of analyzing survey data to understand food preferences for a restaurant would be a. Cleaning a data visualization to remove unwanted patterns. Survey data analysis typically involves iteratively creating visualizations to understand the data (b), cleaning data to correct inconsistencies (c), and filtering responses to focus on specific groups (d). Cleaning data visualizations to remove unwanted patterns is not a standard part of the data analysis process; instead, data visualizations are created to accurately reflect the observed patterns and trends within the data.
When analyzing survey data, determining the most appropriate measure of center, such as the mean, median, or mode, is essential based on the shape of the data, which can be skewed or symmetrical. Also, understanding different sampling designs, whether it is systematic sampling used in the local park study, or recognizing different types of data, such as quantitative discrete data or qualitative (categorical) data, is crucial for accurate interpretation.
