What is an advantage to using the median when examining a set of data?
The median or mode should be used instead of the mean in distributions with extreme outliers. In such cases, the mean can be a misleading measure of central tendency and the median value or the mode value are typically more accurate measures.
What is the uses of mean median and mode in business and industries?
mean can be used in business and industries for comparing purposes. mode as it gives us the value which occurs most often, it can be use to determine the shoe sizes especially in shoe manufacturing industries. median is used to determine the skewness of data
How does mean median and mode apply in life?
They are statistical measures that are used, when appropriate, to summarise the central tendency of a set of data. That is, given a number of observations, these measures can give an indication of the value near which they all are.
What is an outlier in stats?
An outlier, in a set of data, is an observation whose value is distant from other observations. There is no exact definition but one commonly used definition is any value that lies outside of Median ± 3*IQR IQR = Inter-Quartile Range.
Why is the mode not used very much as a measure of central tendency?
The mode is the value with the most data. Unfortunately it tells you nothing about the rest of the distribution. The mean and median provide more useful information in most situations.
Should The mean or median be used in ordinal data?
The median is used when reporting ordinal data.
What is the measure of central tendency for nominal and ordinal data?
The mode can be used with both kinds of data. The median may be used with ordinal data but great care is required if the median falls between two classes of observations.The mode can be used with both kinds of data.

Can the median be used to describe both categorical data and numerical data?
Can the median and mode be used to describe both categorical data and numerical data
How is the choice made between mean and median to describe the typical value related to the shape of the data distribution?
Either can be used for symmetrical distributions. For skewed data, the median may be more a appropriate measure of the central tendency - the "average".
What are the advantages and disadvantages of median?
Median cannot be used for qualitative data (a mode can).The sampling distribution of the median is complicated (the mean is well studied).Median can usually be used for data that can be ordered without there being a ratio scale. For example, "small-medium-large", or "very negative-negative-neutral-positive-very positive". A mean cannot be calculated without arbitrarily assigning a numerical value to the terms.A median is not dependent on all the values which means that it is not distorted by outliers (extreme values).It is easy to find the median value from cumulative frequency charts.
Can the median be used to describe both a categorical data and numerical data?
No. A median makes no sense for categorical data. For example, if you have 10 red cars, 15 blue cars and 20 black cars, what is the median?
Which measure of central tendency is used when data is not numerical?
When the data are not numerical but can be ordered , the median may be used as a measure of central tendency. Put the data in order and choose the middle value. For example, low, medium,medium,low, high etc.
Can the median be used to describe categorical data?
no it cant bec
In deciding which average to use which is most and worst reliable out of mean modal and median?
The mean is used for evenly spread data, and median for skewed data. Not sure when the mode should be used.
What is central tendency of a data?
The term central tendency refers to the middle value or a typical value of the data. It is measured using the mean, median, or mode of the data. Each of these processes is found using different methods, and the one that should be used depends on the situation. I truly hope this helps.
What is the median in a set of data?
The middle value so half the data is above it and half the data is below it. It is often used because extreme values tend to affect it less than other measures of central tendency. If you have an even number of data points, the median is the mean of those two points. ( So you add the two values and divided by two)
