Yes and no. All continuous information has the median, status and mean. Yet, strictly speaking, ordinal information has the median and status But, and nominal information has just one status. This manner is the least used of these methods of central tendency and can only be applied when dealing with specified information. For this reason, that status can take the greatest method of central tendency (as it is the only one appropriate to take) when dealing with specified information. These mean and/or average are normally chosen when dealing with all different types of information, but that does not mean it is never used with these information types (Woods, D., Jan. 2018).

Are the standard deviation or the interquartile range factors? The standard deviation is a measure of the degree to which an individual’s knowledge or understanding about a topic is related to its level of relevance. In other words, if you know something about a topic but don’t know much about it, then you probably have no idea what to expect from your research on that topic. This means you can always find out more about the subject by reading books, articles.

Hello classmates and professor,

The question I decided to answer for this discussion is I read in the newspaper that a study of a new drug for cancer “increased survival by an average of eight weeks.” It turns out that this is a median, and it is used for complicated statistical reasons. But in a perfect world, would you prefer to know the increase in mean or median survival? In the perfect world I would prefer to know the mean vs median. Like Andrew Vickers mentions at the end of the video, “means are good for decision making, medians are good for describing data”. When it comes down to something that a dangerous and life threatening condition it’s probably best and most comforting to know the average survival versus a number that’s calculated by the “middle”. Median is something that results in a number/value and cannot appropriately calculate the survival rate for someone with cancer.
