It means that the blood vessels and blood flow are normal. The part about 'within normal limits' means that there is a range. An example is that the normal range for blood glucose (sugar) is from 70-110. If you have a number somewhere in that range, your blood sugar level is fine.
If you mean lymphocyte, as a percent of total white cells the normal range for adults is 18-40%. 21% is toward the low end but falls within the normal range.
The probability of an event occurring within 5 standard deviations from the mean is extremely rare, as it falls outside the normal range of outcomes.
The reference range for Lymph Absolute is 1.9-8.0 for x10e3/uL. So 3.6 should be within normal range.
2 weeks early is around week 38 which is still within the normal range. It doesn't mean anything special.
It means you're dead.
The average IQ score for the general population is around 100, with most people falling within the range of 85 to 115. This range is considered to be within the normal or average intelligence level. IQ tests are designed to have a mean score of 100 and a standard deviation of 15.
This means that the overall appearance of the heart and mediastinum (the area in the chest that contains the heart and other structures) is within the normal range when observed visually. There are no obvious abnormalities or significant deviations from what is typically seen.
In a normal distribution, approximately 95% of the data falls within 2 standard deviations of the mean. This is part of the empirical rule, which states that about 68% of the data is within 1 standard deviation, and about 99.7% is within 3 standard deviations. Therefore, the range within 2 standard deviations captures a significant majority of the data points.
You need to have all the values within the range to calculate the arithmetic mean .
The average/normal IQ is anywhere between 90 - 110, so this means you are well within the average/normal IQ range.
Within range which sound may be heard.
