The phrase "about normally distributed" is not correct in standard written English.
It may be intended to describe a statistical concept related to normal distribution, but it lacks clarity and completeness.
Example: "The data is about normally distributed, indicating that most values cluster around the mean."
Alternatives: "regarding normal distribution" or "concerning normally distributed data".
The reported C piston-flow age is the age at the median probability (assuming that the age range is normally distributed about the radiocarbon age) of the distribution of the range of ages given in parentheses to the right of the piston-flow age (Table 1) (Stuiver and Reimer 1993).
Assuming luck to be normally distributed, they are about as far off on the right tail of the curve as you can possibly get.
Pay is normally distributed about a week after a pay period ends.
Figure 1 shows that the residuals are normally distributed about a straight line which means that the errors are normally distributed.
The error term is a stochastic process that is normally distributed about a zero mean and a constant variance, (varepsilon_{t} sim N 0, sigma^{2} )).
Since the MADi and MAD/MAF variates are approximately normally distributed about zero and uncorrelated, a good candidate for the thresholding is in terms of standard deviations about the mean for each component.
In that case b may say that for this kind of device the measurement errors are normally distributed about whatever value a given gravitational theory predicts, with some specified standard deviation that is characteristic of the device.
The maximum likelihood technique is chosen in this paper because of two reasons: one is that this technique has been applied efficiently in a large set; the other is that it has well-documented favorable properties, such as being asymptotically consistent, unbiased, efficient and normally distributed about the true parameter values.
An analysis of the residuals (Fig. 3 insert) revealed that they were essentially negligible and normally distributed about zero.
Fluorescence lifetimes from the pixels of imaged non-parasitized EM (nEM) were normally distributed about an average value of ≈1600 1800 ps (Fig. 1A).
