Definition: Measures of Dispersion. PDF MMeasures of Centereasures of Center - Big Ideas Learning Lesson Planet: Curated OER. The median is not swayed as much by outliers as the mean is. The formula for mean is the total sum of terms divided by the number of terms. All three of these sets of data have a mean of 5 and median of 5, yet the sets of scores are clearly quite different. If there are outliers and the data doesn't appear to be normally distributed, then the median is a better choice than the mean because it more accurately reflects the true midpoint of your data. Adding this to our sample, our mean is now: \[\dfrac{15 \cdot 6+20 \cdot 8+25 \cdot 11+30 \cdot 17+35 \cdot 19+40 \cdot 20+45 \cdot 12+50 \cdot 7+5000 \cdot 1}{101}=\frac{8390}{101}=83.069 \nonumber \].

About This Quiz & Worksheet These assessments will check your knowledge of which measure of central tendency should be used in a given situation. Using two real-world data sets, students will calculate the measures of center and variation without an outlier then with an outlier. The mean is the average of the data and is found by adding up all the values and dividing by the number of values. This measure of variation is greatly affected by outliers. One solid method to help you establish the identity of what the information is telling you is to locate the center of of the statistics itself.

Similarly, we can see that the first quartile of the survivors is larger than the median weight of those that died, meaning that over 75% of the survivors had a birth weight larger than the median birth weight of those that died. If there are an odd number of values, the middle value is the median. The median is the number that falls in the exact center of all the measurements, while the mode is the number that occurs most frequently. The mean, median, and mode are measures of center.
