Extreme high or low values in a data set, known as outliers, can significantly skew the mean. For instance, a few very high values can inflate the mean, making it higher than the central tendency of the majority of the data. Conversely, extreme low values can drag the mean down, misrepresenting the typical value of the dataset. This sensitivity makes the mean less reliable as a measure of central tendency when outliers are present.

When computing Standard deviation should you eliminate the extreme values?
Generally not without further reason. Extreme values are often called outliers. Eliminating unusually high values will lower the standard deviation. You may want to calculate standard deviations with and without the extreme values to identify their impact on calculations. See related link for additional discussion.
What are the advantages and disadvantages of Range mode median and inter quartile range?
RangeAdvantage - Shows the spread of the resultsDisadvantage - Does not take into account any 'clustering' of results in a set of data.- It is affected strongly by outliers (very high or very low results).ModeAdvantage - Shows the most popular result for non-numerical dataDisadvantage - Does not always give one value, it is not unique- It can only be used on a set of data where one or more values are repeated.MedianAdvantage - Extreme values do not affect the median as strongly as they do the mean- Useful when comparing sets of data- It is uniqueDisadvantage - It does not take into account the spread of results or show clustering of data, much like the range.Interquartile RangeAdvantages - Ignores extreme values- easier to use than the range when comparing data.Disadvantages - Er, I'll get back to you on that. Maybe the IQR has no flaws?
What if I have a very high standard deviation?
The larger the value of the standard deviation, the more the data values are scattered and the less accurate any results are likely to be.
What does a skewness of 1.27 mean?
A skewness of 1.27 indicates a distribution that is positively skewed, meaning that the tail on the right side of the distribution is longer or fatter than the left side. This suggests that the majority of the data points are concentrated on the left, with some extreme values on the right, pulling the mean higher than the median. In practical terms, this might indicate the presence of outliers or a few high values significantly affecting the overall distribution.
What is a high outlier?
A high outlier is a data point that significantly exceeds the rest of the data set, falling well above the expected range or distribution. It can indicate variability in the data, errors in measurement, or unique occurrences. In statistical analysis, high outliers can skew results and affect the overall interpretation, so they are often examined closely to determine their cause and impact. Identifying high outliers is crucial for accurate data analysis and decision-making.
Do extremely high or low scores affect the value of the median?
No, extremely high or low values will not affect the median. Because the median is the middle number of a series of numbers arranged from low to high, extreme values would only serve as the end markers of the values.
What are extreme values?
Extreme values are the maximum or minimum values of a function or a dataset. They represent the highest or lowest points in the data set and are useful for understanding the overall characteristics or outliers in the data.
What is called when extreme conditions like high temperature and extreme Ph values change the shape of an enzyme?
Danze16
What are extremely high or low values in a data set called?
Values that are either extremely high or low in a data set are called 'outliers'. They are typically 3 standard deviations or more from the mean.
Extremely high or low values in a data set are called?
Outlier

What is the criticized of high low method?
It ignores much of the available data by concentrating on only the extreme points.
Which of the following is least affected if an extreme high outlier is added to your data mean median or standard deviation or ALL?
The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.

Can the heat affect my inr?
Yes, high temperatures can affect the stability of warfarin, which can in turn affect your INR levels. It's important to store your medication properly and avoid exposing it to extreme heat to ensure its effectiveness. If you experience unusually high temperatures, it's a good idea to consult with your healthcare provider to potentially adjust your warfarin dosage.
