Which measure best represents data... mean, median or mode?
Thank you!! :)

It depends upon the data and your purpose in using the data.
Earlier you asked about salary data. Mode is not representative of this data. That leaves median and mean to consider.
I suggest you find the median and the mean for your data, and then decide which is more representative for your purpose.
To determine which measure best represents a given data set, we need to understand the characteristics and purpose of each measure: mean, median, and mode.
1. Mean: The mean is calculated by summing up all the values in a data set and then dividing by the total number of values. It is also commonly referred to as the average. The mean represents the central tendency of the data and is sensitive to extreme values or outliers. It is best used when the data set is symmetrically distributed without significant outliers.
2. Median: The median divides a data set into two equal halves, with half the values being below and half above. It is the middle value when the data set is sorted in ascending or descending order. The median is less affected by outliers and extreme values, making it useful when the data set is skewed or contains outliers.
3. Mode: The mode represents the most frequently occurring value(s) in a data set. Unlike the mean and median, the mode can be applied to both numeric and categorical data. It is particularly useful for identifying the most common responses or categories within a dataset.
To determine the best measure, consider the characteristics of your data set. The mean provides an overall average, but if your data is skewed or contains extreme values, it may not accurately represent the central tendency. In such cases, the median would be a better choice as it is less affected by outliers. The mode, on the other hand, is appropriate for categorical or discrete data when identifying the most common value(s) is of interest.
Without having more information about your specific data set, it is difficult to determine which measure would be most appropriate.
