Extremely high or low values in a data set are called outliers. Outliers can significantly affect statistical analyses, as they may skew results and lead to misleading interpretations. They can arise from variability in the data, measurement errors, or may indicate a novel phenomenon worth investigating further. Identifying and understanding outliers is crucial for accurate data analysis.

What characteristic of data is measure of the amount that data values vary?
The characteristic of data that measures the amount that data values vary is called "variability" or "dispersion." Common statistical measures of variability include range, variance, and standard deviation, which quantify how spread out the data points are from the mean. High variability indicates that the data points are widely spread, while low variability suggests that they are clustered closely around the mean.
Which numerical measure of center is most affected by extremely high or low numeric data?
Mean.
What is the Extreme high or low values in a data set which affect the mean?
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.
Why are averages misleading?
Averages can be misleading because they may not accurately represent the underlying data, especially when outliers or skewed distributions are present. For example, a few extremely high or low values can distort the average, giving a false impression of the typical case. Additionally, averages fail to convey important information about the variability or distribution of the data, which can lead to oversimplified conclusions. Therefore, relying solely on averages can obscure significant insights and nuances in the data.
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
Is the mode affected by extremely low or high values?
No, extremely low or high values are affected by the mean.
When measures of central tendency are not affected by extremely low or extremely high values?
Mode and median.
Which measures of central tendency are not affected by extremely low or extremely high values?
Mode and Median
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.
