Consequently, Chebyshev’s Theorem tells you that at least 75% of the values fall between 100 ± 20, equating to a range of 80 – 120. Conversely, no more than 25% fall outside that range. An interesting range is ± 1.41 standard deviations.

WebbA binary variable with equal probabilities has mean 0.5 and standard deviation 0.5. The usual standardized predictor (scaled by one standard deviation) then takes on the values ±1, and a 1-unit difference on this transformed scale corresponds to a difference of 0.5 on the original variable (for example, a comparison between x = 0.25 and x ... Webb29 okt. 2024 · The range is the difference between the maximum score and the minimum score within a data set. In this example, the range is the difference between 98, the highest score obtained, and 11, the lowest. As can be seen, it is very easy to calculate it. However, it can also be easily affected by outliers, in this case 11, 25 and 98. hut bonn https://transformationsbyjan.com
