Between Mean Median and Mode which are affected most by an outlier?
The mean is affected the most by an outlier.
Which measures of central tendency are not affected by extremely high values?
Mode and Median
Is the median affected by the mean?
The median is the value which seperates the upper and lower half of a set of numbers. The mean is the average value between two or more numbers. In calculating a set of numbers, specifically a set of averages, the median may indeed be effected by the mean.
Is the median more affected by errors in data than the mean?
well, they're both affected. you will get both answers wrong if you make a mistake so it doesnt matter which one is more important, just pay attention
What is an ouutlier effect on the median?
An outlier pulls the median towards it. For example 1,2,3 Median=2 1,2,3,7 Median=2.5
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.
Between Mean Median and Mode which are affected most by an outlier?
The mean is affected the most by an outlier.
Which measures of central tendency are not affected by extremely high values?
Mode and Median
What measures of central location is affected most by extreme values?
The mean is most affected. Mode and Median are not influenced as much by outliers.
Why calculate for the mean and median in relation to a sample?
Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.
Which of three three measures of central tendency is most affected by extreme scores?
Of the mean, median and mode the mean would be most affected.
How would the outlier affect the mean and median of the data?
An outlier will pull the mean and median towards itself. The extent to which the mean is affected will depend on the number of observations as well as the magnitude of the outlier. The median will change by a half-step.
Which measures of central tendency are not affected by extremely low or extremely high values?
Mode and Median
When measures of central tendency are not affected by extremely low or extremely high values?
Mode and median.
Is the median affected by the mean?
The median is the value which seperates the upper and lower half of a set of numbers. The mean is the average value between two or more numbers. In calculating a set of numbers, specifically a set of averages, the median may indeed be effected by the mean.
What measures are not affected by outliers?
Median, mode, quartiles, quintiles and so on, except when you get to very large number of percentiles.
Median or the first quartile is least affected by one value which is significantly higher or lower than the rest?
An outlier.
