Average Formula:
From: | To: |
The average (arithmetic mean) is a measure of central tendency that represents the sum of all values divided by the number of values. It provides a single value that summarizes a dataset.
The calculator uses the average formula:
Where:
Explanation: The calculator sums all valid numbers entered and divides by the count of numbers.
Details: Averages are fundamental in statistics, used to summarize data, compare groups, and make predictions. They're essential in fields like economics, science, and business analytics.
Tips: Enter numbers separated by commas (e.g., 5, 10, 15). The calculator will ignore any non-numeric values. At least one valid number is required.
Q1: What's the difference between mean, median and mode?
A: Mean is the average, median is the middle value, and mode is the most frequent value. Each measures central tendency differently.
Q2: When shouldn't I use the average?
A: For skewed distributions or datasets with outliers, the median may be more representative than the mean.
Q3: How many decimal places should I use?
A: This depends on your data's precision. The calculator shows 2 decimal places by default.
Q4: Can I calculate average of percentages?
A: Yes, but be cautious - sometimes weighted averages are more appropriate for percentages.
Q5: What if I enter non-numeric values?
A: The calculator will ignore any non-numeric entries and calculate the average using only valid numbers.
