Assignment Instructions

DATA INFORMATION IS IN THE BIGMART DATA SALES INKAGGLE. THE LINK TO THE TRAIN DATASET IS BELOW;

selected dataset: https://www.kaggle.com/datasets/brijbhushannanda1979/bigmart-sales-data

Bigmart data sales WITH 8524 rows and 13 variables

For this assignment, complete an exploratory data analysis. This means: getting a sense of the data

• creating visualizations to represent the data; include histograms, boxplots, scatterplots etc. as needed
• obtain descriptive statistic of the data
• finding subsets of data and getting descriptive statistics for each subset
• create visualizations for subset data

As you explore your data and see it visualized, you may find that your dataset has extreme outliers, incomplete data or just wrong data. If this is the case, you will need to clean your data to get a better understanding of the data. Once you have cleaned the data, perform the exploratory analysis again.

In your report be sure to:

• Describe your dataset.
  • What is the purpose of the dataset? What is your data source?
  • What kind of data is included? Is it all text data, is it numerical?
  • Describe the data fields including the title, the data type, the data description, etc.
  • How many rows of data are there? how many fields?
• How many rows of data are there? how many fields?
• Describe any data cleaning you did
• Provide visualizations of the key data and subset data of interest. This should be done for categorical data, discrete data and continuous data.
• Provide descriptive statistical tables for key data fields of interest.
• Provide analysis above and beyond the graphs and tables. Explain what the tables and visualizations tell you about the data.

Format

Present your Exploratory Data Analysis in a report. Incorporate visualizations and tables into the textual analysis of your report. If appropriate, add an appendix of additional data tables and graphs.

The report should follow this flow:

Introduction: introduce the data, its purpose, the sources, the reason for choosing the data and what you hope to learn from the data. Incorporate a discussion of the data cleaning methods used.

Data Analysis: This is the body of the report where you provide descriptions of the data, basis statistical measures, graphs, tables and analysis.

Summary: Summarize the report. Identify the key take-aways from your analysis. Describe what you want to explore further about your data. Identify questions you want to answer with the data.

Your report must, including all graphs but excluding the appendix.
