Homework 3: Let me count the ways...
The goals of this homework are:
- Demonstrate/Practice your ability to employ counting techniques.
- Download this workbook.
- (10%) Modify and maintain the About tab as you work.
- Add your name.
- Discuss any data errors you find. (I don't think there are any)
- Discuss any major techniques you employ (probably not much)
- Maintain a list of sheets and contents.
- (10%) Document your work by
- Naming ranges used
- Naming worksheets appropriately.
- Name the cells in raw data
- Click in cell A1 of the sheet
- press and hold ctrl shift
- Press the down arrow once
- Press the right arrow once
- This should select the entire range.
- Name the columns in the range.
- (30%) Basic Analysis
- Create a new worksheet, Basic Analysis.
- Copy the column headers from RawData to this sheet, B1:L1
- Add a row describing the data as text, date, currency or numeric
-
- Add the following labels in row A
-
- I am organizing this so you can develop a set of formulas in column B and copy it across to column L
- You will not use range names in this (unless someone knows something clever)
- Do use addresses
- Note the data goes from 2:2584
- Remember RawData!A2:A2584 will give access to the data in row a on the RawData table.
- Perform a basic analysis of the name data in column B
- In B3 develop a formula that will count all the non-blank cells in the name data.
- In B4 develop a formula that will count all numeric cells in the name data.
- In B5 develop a formula that will count all blank cells in the name data.
- In B7 develop a formula that will count the number of unique cells in the name data.
- In B9-B13, if the data is identified as something other than text in B2, compute the five number summary. You should do this in ALL columns, but text columns should display a blank.
- Copy these formulas across to column L to compute the five number summary for all data.
- Compute outliers for any currency or numeric data.
- The interquartile distance (d) is the Q3-Q1
- The interquartile range (IQR) is [Q2-1.5d, Q2+1.5d]
- Any value that falls outside of this range is an outlier.
- In row 18, compute the number of outliers for this dataset.
- Format all cells in this table appropriately.
-
- I spot checked this, but there may be errors.
- I tried to draw box and whisker plots, but the outliers are too far out, perhaps a log scale?
- Feel free to draw any graphs of non-text data you feel are appropriate.
- (30%) Text Analysis
- I feel we should analyze the text with fewer than 40 unique values.
- Make a new worksheet called Text Analysis
- You did add this to the About sheet, right?
- For country, build a basic frequency distribution and histogram
- Extract the unique countries.
- Build frequency counts
- Sort by frequency
- I used a column chart for my graph.
-
- For currency do the same
- But add a column to count the number of countries that use each type of currency.
-
- For state
- Find the frequency for each project state.
- Find the average backers for each project state.
- Find the average pledged, in US Dollars, for each project state
- Find the Average goal, in US Dollars, for each project state.
-
- (20%) Exploring Further.
- Add a worksheet labeled Explore
- Add an input area where the user can change country and state
-
- Add an area where the following are calculated based on the user's input
- The number of projects matching the criteria
- The average goal, in US dollars, fore projects matching the criteria
- The max/min goal, in US dollars, fore projects matching the criteria
- The average pledged, in US dollars, fore projects matching the criteria
- The max/min pledged, in US dollars, fore projects matching the criteria
-
- Build the following table, displaying the number of backers for each currency for each project state
- You should develop a single formula that is copied to all cells.
-
- Compute, using a single formula, the highest pledge per backer for any project.
- Based on the previous result, find the name of the project with the highest pledge per backer rate.
