Statistical Measures

Mean (Average)

The arithmetic mean is the sum of all values divided by the number of values.

Mean (μ) = (x₁ + x₂ + … + xₙ) / n

Median

The middle value when data is arranged in order. For even number of values, it’s the average of two middle values.

Standard Deviation

Measures the amount of variation in a dataset.

Standard Deviation (σ) = √[(Σ(x – μ)²) / n]

Visualization Types

Histogram

Shows the distribution of numerical data by grouping data into bins.

Box Plot

Displays the five-number summary: minimum, first quartile, median, third quartile, and maximum.

Scatter Plot

Shows the relationship between two variables by plotting points on a coordinate system.

Frequently Asked Questions (FAQ)

Q: What format should my data be in?
A: Data should be in CSV format with values separated by commas. Each line represents a new row of data.
Q: How do I create a scatter plot?
A: Your data needs at least two columns. The first column will be used for X-axis values, and the second column for Y-axis values.
Q: What does the box plot show?
A: A box plot shows the distribution of your data through quartiles. The box represents the interquartile range (IQR), with the middle line showing the median. Whiskers extend to show the rest of the distribution.
Q: How is the standard deviation calculated?
A: Standard deviation is calculated by taking the square root of the average squared differences from the mean. It measures how spread out the numbers are from their average.
