此次作业主要考察统计学的基本操作,项目内容都在excel表格中完成,part 2-8分别对应不同的考察内容,比如charting,ANOVA,和pivot
Descriptive statistics
■ Collecting, presenting, and describing data
Inferential statistics
■ Drawing conclusions and/or making decisionsconcerning a population based only on sample data
Probability
■ Chance that a particular event will occur
Part 2 Charting – Identify each state # with its 2-digit abbreviation.

Part 3
Calculate Descriptive Statistics, with a 99% confidence interval from Data Analysis, for the in-state tuition for your combined data. For your four states combined, display the full set of Data/Data Analysis/Descriptive Statistics below, with one aggregate + 99% confidence level value for your four states combined.
Part 4
Pivot Table: With any three variables in the data set, create either a table or a graphic using Pivot Tables.
See the two YouTube videos listed above.
1. Copy all your data for your four states into the Pivot space (or new spreadsheet). | |||||
2. The pivot table report/chart needs to reflect at least 3 of these variables. | |||||
3. Metric (counts, averages, etc.) are appropriate. | |||||
4. The chart must make sense. | |||||
5. Include appropriate title/labels. |
Part 5
1. Display only the relevant column(s) of data, with column headings. | |||||
2. Please include your Excel full correlation matrix over the variables. | |||||
3. Apply conditional formatting over the correlation matrix. | |||||
4A. Select and copy 2 of the variables; plot the data for these 2 variables as one combined scatter diagram reflecting the data for your four states in the aggregate. | |||||
4B. Include the title, and label both axes. |
