What is the difference between Analysis and Analytics.

Analysis:
Consider you have a huge data set containing data of various types. Instead of tackling the entire dataset and running the risk of becoming overwhelmed you separated into easier to digest chunks and study them individually and examine how they relate to other parts and that’s analysis in a nutshell.
One important thing to remember however is that you perform analyses on things that have already happened in the past such as using an analysis to explain how a story ended the way it did or how there was a decrease in the cells last summer. All this means that we do analyses to explain how and or why something happened.
总结：Analysis is that you perform analyses on things that have already happened in the past and do analyses to explain how and or why something happened.

Analytics:
It refers to the future instead of explaining past events. It explores potential future ones. Analytics is essentially the application of logical and computational reasoning to the component parts obtained in an analysis and in doing this you are looking for patterns in exploring what you can do with them in the future.

Analytics 分为两部分。
第一部分：Qualitative:
This is using your intuition and experience in conjunction with the analysis to plan your next business move.
第二步：Quantitative:
This is applying formulas and algorithms to numbers you have gathered from your analysis.

举个例子：
You are an owner of an online clothing store. You are ahead of the competition and have a great understanding of what your customers needs and wants are. You’ve performed a very detailed analysis from women’s clothing articles and feel sure about which fashion trends to follow. You may use this intuition to decide on which styles of clothing to start selling. This would be qualitative analytics but you might not know when to introduce the new collection. In that case relying on past sales data and user experience data you could predict in which month it would be best to do that. This is an example of using quantitative analytics.
意思就是，你是网店的老板，你想要卖衣服，提高收入。你从杂志上看到什么款式的衣服是未来流行的，这个方法就叫做Qualitative analytics。 虽然你知道什么款式最流行了，但是你不知道什么时段拿出来销售是最好的。这时候你就将你之前整理的图表，看到什么时段卖的最多衣服，这个方法就叫做Quantitative analytics。

You can combine these areas with analyses. Also you could perform qualitative analysis to explain how or why a story ended the way it did. And you can perform quantitative analysis working with past data to explain how sales decrease last Summer.
