What is a TSV file?
TSV stands for Tab-Separated Values. It's a plain text file format where data is organized into columns and rows. Each row represents a data point, and each column represents a different attribute or variable. The values within each cell are separated by tabs.
How is sample-stats.tsv structured?
The sample-stats.tsv file usually follows a consistent structure. Here's a typical example of the content:
# Column headers
column1 column2 column3 column4
# Data rows
value1 value2 value3 value4
value5 value6 value7 value8
...
The first row usually contains the column headers, which define the names of the variables. The subsequent rows represent the actual data points, with each value separated by tabs.
What kind of data does sample-stats.tsv contain?
The specific data in a sample-stats.tsv file can vary widely, depending on the context. However, it often contains statistical summaries of a dataset, such as:
- Means: Average values for each variable.
- Standard Deviations: Measures of how spread out the data is for each variable.
- Percentiles: Values that divide the data into equal segments.
- Counts: Number of data points for each category.
