Witryna20 maj 2024 · In some cases, this can be corrected by transforming the data via calculating the square root of the observations. Alternately, the distribution may be exponential, but may look normal if the observations are transformed by taking the natural logarithm of the values. Data with this distribution is called log-normal. WitrynaI made normal log, log 10, box-cox to transform these data but they are still not normally distributed.

WitrynaThe skewness value can be positive or negative, or even undefined. If skewness is 0, the data are perfectly symmetrical, although it is quite unlikely for real-world data. As a general rule of thumb: If skewness is less than -1 or greater than 1, the distribution is highly skewed. If skewness is between -1 and -0.5 or between 0.5 and 1, the ... WitrynaWhen plotting a histogram, the data appears skewed to the right. Was going to use the percentile function to establish a 95% ci in excel, but I'm sure this function assumes normality. ...
