there are. Median is the middle score in a distribution; half the scores are above it and half the scores are below it. Mode is the most frequently occurring score in a distribution. A skewed distribution is when the distribution is leaning toward one side. It is the measure asymmetric probability and its real value of data. A skewed would be like a group of random people who take an IQ test all score above average would be skewed upwards. The three measures of central tendency‚ mean‚ median‚ and mode

Mean‚ Median‚ Mode‚ and Range Mean‚ median‚ and mode are three kinds of "averages". There are many "averages" in statistics‚ but these are‚ I think‚ the three most common‚ and are certainly the three you are most likely to encounter in your pre-statistics courses‚ if the topic comes up at all. The "mean" is the "average" you ’re used to‚ where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. To find the median‚ your

Using the Standard Deviation You made a number of observations about the data sets for the school activities. You used mean and median to measure the center of the data‚ and you used the interquartile range (IQR) to measure the spread. When outliers are present‚ the median and IQR are used to measure center and spread because they are unaffected by extreme values. When the data appears to be symmetric and there are no known outliers‚ the mean and standard deviation (another measure of spread)
