One very common technique is to find the average, or mean of all of the values in your data set. In this video, learn how to find an average in Mathematica 11, as well as how to identify the median, or middle value, and find the most common values
- [Instructor] When you gather data for your research…you can analyze it using a number of techniques.…One very common technique is to find the average…or mean of all the values in your dataset.…In this movie I will show you how to find an average…in Mathematica 11.0 as well as how to identify…the median or middle value, and also the most common…values in the list.…To begin my analysis I will need a list of values…so I'll call it list8…equal and then a left…curly bracket to start my list…and I'll type in seven comma 24 comma 81…comma 95 comma 81 comma five, and then shift + enter.…
I have my list and one thing to note as preview…is that the number 81 is in the list twice so…it's the most common value.…Well let's start by analyzing the average of the values…and I won't assign these to any variables,…I'll just display the result using shift + enter.…If I want to find the average I can use the mean key word…so I'll type mean, and this stands for arithmetic mean…or average, and a left square bracket and the name…
