Data Preview and Summary

After importing your datasets, it's crucial to preview and analyze the data to ensure its quality and readiness for further processing. This guide will help you understand how to preview your data and perform univariate analysis using the Data Preview tab.

1. Accessing the Data Preview Tab​

Steps:

  1. Navigate to the Datasets Section:
    • From the main dashboard, click on the "Datasets" tab to access your list of imported datasets.
  2. Select a Dataset:
    • Click on the dataset you want to preview. This will open the dataset details page.
  3. Open the Data Preview Tab:
    • Within the dataset details page, locate and click on the "Data Preview" tab.

2. Previewing Data​

Steps:

  1. View Data Table:
    • The Data Preview tab displays the data in your dataset in a tabular format.
    • Scroll through the table to get an overview of the data structure, including columns and sample values.
  2. Column Information:
    • Column headers are displayed at the top of the table, showing the names of each attribute.
    • Click on a column header to view additional details such as data type, unique values, and missing values.
  3. Filtering and Sorting:
    • Use the filter options above the table to narrow down the data displayed based on specific criteria.
    • Click on column headers to sort the data in ascending or descending order.

3. Performing Univariate Analysis​

The Data Preview tab in Kranium AI provides tools for performing univariate analysis, which focuses on understanding individual variables in your dataset.

Steps:

  1. Access Univariate Analysis Tools:
    • Within the Data Preview tab, locate the "Univariate Analysis" section.
  2. Summary Statistics:
    • Use the ‘+’ button on the Variable Analysis section to add columns from your dataset for analysis
    • Use the statistics to understand the central tendency and dispersion of the data.

4. Interpreting Results​

Steps:

  1. Analyze Summary Statistics:
    • Review the summary statistics to understand the central tendency (mean, median, mode) and dispersion (standard deviation, range) of the variable.
    • Identify any unusual values or patterns in the data.
  2. Examine Frequency Distribution:
    • Use the frequency distribution to see how often each category occurs.
    • Identify dominant categories and any potential imbalances in the data.
