community dentistry: rate ratio and proportion
Certainly, I can explain the three statistical concepts you're referring to: mean, median, and mode. 1. **Mean**: The mean is the most commonly used measure of central tendency. It is calculated by adding up all the values in a data set and then dividing by the total number of values. The mean is sensitive to extreme values, often called outliers. If there are outliers in the data, they can significantly affect the mean, pulling it in the direction of the outliers. 2. **Median**: The median is the middle value in a data set when the values are arranged in ascending or descending order. If there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values. The median is not affected by outliers as much as the mean, making it a more robust measure of central tendency in skewed distributions. 3. **Mode**: The mode is the value that appears most frequently in a data set. A data set can h
