I use it in class when looking at my student's scores... Often I look at mean, median, and mode to decide to reteach a concept or not.
MEAN
You could use mode over median or mean when calculating probability. Mode calculates the greatest number of times an object or number will appear.
Perhaps I have some difficulty understanding your question. The mean, median and mode are measures of the center of data or measures of centrality.
If you ask what is the most popular dish served in the restaurant you are seeking the mode.
mean is the average of numbers in the data set mode is the most frequently occurring value in a data set and median is the middle number of the data set so you would use mean
Mean is the average you add all the numbers and divide the total by the number of numbers that you added. you would use it rather thank median and mode basically when it asks you to find the mean or to find the average
a stem and leaf plot
to work out various different types of averages
We use mean for measure the central tendency and mode for observed most common value of observation.
You use mean when you want to find the average of data. You use median to find the middle of a piece of data, ordered from least to greatest. If there is 2 medians, then find the average of those 2 numbers. You use mode when you are trying to figure out the most common piece of data. There can be more than 1 mode.
