Frequently Asked Questions
What is the difference between mean, median, and mode?
Mean is the average of all values (sum divided by count), median is the middle value when data is sorted, and mode is the most frequently occurring value. These are the three main measures of central tendency in statistics.
How do you calculate the mean of a data set?
To calculate the mean, add all values in the data set and divide by the number of values. Formula: Mean = (Sum of all values) ÷ (Number of values). For example, the mean of 2, 4, 6 is (2+4+6)÷3 = 4.
What is the median and how is it found?
The median is the middle value in a sorted data set. For an odd number of values, it's the middle value. For an even number of values, it's the average of the two middle values. The median is less affected by outliers than the mean.
Can a data set have multiple modes?
Yes, a data set can have multiple modes (bimodal, trimodal, etc.) if multiple values occur with the same highest frequency. If all values occur equally, there is no mode. If no value repeats, the data set has no mode.
What are quartiles and how are they calculated?
Quartiles divide a data set into four equal parts. Q1 (25th percentile) is the median of the lower half, Q2 is the overall median (50th percentile), and Q3 (75th percentile) is the median of the upper half. They help understand data distribution and identify outliers.
How do you identify outliers in a data set?
Outliers are values that fall outside the range of Q1 - 1.5×IQR to Q3 + 1.5×IQR, where IQR is the interquartile range (Q3 - Q1). Our calculator automatically identifies potential outliers using this standard method.
