I used to work for a wholesaler of college text books and faced a similar situation. I needed to copy a very large PDF document and transfer its content to Excel.
I remember refusing to do so and asking a coworker to put this data microsoft excel 2013 data analysis and business modeling problem solutions free download a different format. I was trying everything under microosft control to нажмите для продолжения that PDF file.
Unfortunately, in the end I had no choice but to roll up my sleeves and get the job done. As a data businees, you would probably spend most of your time in the data analysis life cycle cleaning the data.
In modelimg words, you will gather data and organize it in a format you can work with. Munging and data wrangling are other terms you may hear that refer to this step of the process. Other common issues are numbers formatted as strings, missing values, extra spaces, and so on. After you gather and prepare your data, you are now ready to analyze it.
Your main goal up until now was to get your exce, into Excel; this is our comfort zone where we know ссылка на подробности can work with data. What do I mean when I say analyze your data? Нажмите для продолжения, this means that it is time to get your inquisitive and curious hats on. If you don’t have any of these, then it is time to analysie like a detective, Inspector Gadget style if you’re old enough to remember who he is.
In this step, we begin with inspecting every column one by one. For example, let’s say that the first column was called Revenue and the нажмите чтобы увидеть больше column was called Product Name. We would expect the Revenue column to have numbers in each of the values and the Product Name column to have strings as the values associated with this column.
We will then look for any missing values, the largest number, and the smallest value. We might also take a look at the distinct values in the Product Name column and look for any misspelled words.
Источник you trying to solve a problem? Are you trying to predict the next year’s revenue? Did you ask for some background of the task you were assigned to do? Remember to ask all these questions to whoever is going to receive your daa for feedback along the way. The last thing that you might avoid is that when you complete the analysis, you are told that you were analyzing or solving the wrong problem.
You may also spend a lot of time figuring out what certain columns mean if you actually have the data to complete the task. This is where the fun begins; you are now at a point where you can tell your story.
At this point, you should know everything about your data, such as where it came from and how it was busienss or organized, and you should have completed the task you were assigned, at least in theory. For example, if you were microsoft excel 2013 data analysis and business modeling problem solutions free download to simply create a line chart with the monthly sales for the year, then this is where you should be at this stage.
The data should be in Excel, the sales data should be aggregated on a monthly basis, and you should already have an idea of how to create and place your line chart.
Before you spend an hour or so making your final spreadsheet look good, create a simple mockup and get feedback from your end user. I know that this is not always applicable to every situation, but getting feedback along the way will save you a lot of time from redoing the work at a later stage.
Another little known fact is that people just change their minds or sometimes change their requirements, so always build your spreadsheets as flexible as possible. In our example, you may be asked to switch the data from quarterly to monthly for an analysis at the last minute.
They may want the data over the past 5 years and a bar chart instead of a line chart. My advice to you is very simple; expect changes every single time.
