Greater standard deviation means
WebMar 28, 2024 · Standard deviation can be greater than the variance since the square root of a decimal is larger (and not smaller) than the original number when the variance is less than one (1.0 or 100%). WebThe standard deviation uses the same units as the variable. A higher standard deviation value indicates greater spread in the data. A good rule of thumb for a normal distribution is as follows: Approximately 68% of the values fall within one standard deviation of the mean. 95% of the values fall within two standard deviations.

WebA standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more … WebA normal probability model is a poor choice for modeling time-to-event outcomes. If the probability model is exponential, the variance is related to the square of the mean, so with an SD greater than the mean, we can infer that there is some evidence the mean is greater than "1" on whichever units you have used to measure the outcome.
