You will be using your frontal left lobe of brain when doing any mathematical calculations or logical thinkings. At a point of time, when you are more into mathematics, you may start forgetting your family, miss your routine chores, lose your creativity skills, etc. Mathematics is indeed difficult, mathematicians (or people who have such brain) would be nerd, and the possibility of a mathematician to become a great leader is very low. I'm also learning mathematics to make my brain younger, without trying to miss the other aspects in life :)
Outliers are observations that are way out of line with other observations.
There are several definitions of outliers - based on the quartiles and the interquartile range. Values
smaller than Q1 - k*IQR
or
larger than Q3 + k*IQR
for some positive value k are considered outliers.
The definition may be asymmetrical if the variable is believed to be so distributed.
No, median is not an outlier.
0s are not the outlier values
Depends on whether the outlier was too small or too large. If the outlier was too small, the mean without the outlier would be larger. Conversely, if the outlier was too large, the mean without the outlier would be smaller.
No. A single observation can never be an outlier.
The answer depends on the nature of the outlier. Removing a very small outlier will increase the mean while removing a large outlier will reduce the mean.
Calculate the mean, median, and range with the outlier, and then again without the outlier. Then find the difference. Mode will be unaffected by an outlier.
The outlier is 558286.
1,2,3,4,20 20 is the outlier range
there is no outlier because there isn't a data set to go along with it. so theres no outlier
Yes, it will. An outlier is a data point that lies outside the normal range of data. This means that if it is factored in the mean will move in the direction the outlier is, really high if the outlier was high, and really low if the outlier was low.
the most common cause of an outlier is an error in the recording of data.
A single observation cannot have an outlier.
