Tzintzuntzan Exercise

PART 1 – Household Selection and Data

1. Look at the photos and maps of the town and Block 20 [(see map of the entire town, the map of Block 20 with all houses, and the map of Block 20 with occupied houses), the aerial photos (see aerial photo for the entire town, the aerial photo for Block 20 and the surrounding eight blocks, and the aerial photo of Block 20 alone)].

2. Look at the Guide to the household data spreadsheet. This Guide provides the name and column location of each variable and how it is coded (i.e., the values taken by the variable). You may want to print out this guide in order to see all of the variables and their values together.

3. Look at the Block 20 household data spreadsheet. The rows correspond to each case (i.e., household), while the columns correspond to each variable (i.e., feature of the household).

4. Copy and paste the data set for Block 20 into a spreadsheet.

5. If the selected variables are coded as “0” or “1” (meaning “absent” or “present”), calculate the PERCENTAGE of the households in Block 20 that have each of these variables. If the variables have a distribution other than “0” and “1, then calculate the mean, the median, the mode, the minimum, and the maximum. For example, the variable “No. of rooms” has a range from 1-15 and the "Level-of-Living-Score" has a distribution range of 0-50. Save and print out the results as an Appendix.

PART 2 – Data for a Section (Barrio) of Tzintzuntzan

1. Do the same work (Part 1, steps 4 through 5) for each of the five sections of the community: El Rincón (farthest to the west end of town, corresponding to Blocks 00-17), El Centro (around the main street and the plazas, corresponding to Blocks18-21, 25-28, 30-36, and 39-42), Pueblo Nuevo (to the south end of town, corresponding to Blocks 22-24, 29, 37, and 44), El Llanito (a new section to the east, below the yácatas, corresponding to Block 43 in all of its several parts), and Yahuaro (an old area to the northeast, corresponding to Block 38 and Blocks 45-57). For orientation, you can look again at the aerial photo of the town.

PART 3 – Data for the Entire Community

1. Do the same work as in Part 1 and Part 2 for all of the households in the entire community (corresponding to Block 00 through Block 57). See the Community Data Sheet.

Note: I have excluded data on households located in the peripheral colonias of Lázaro Cárdenas (Block 61L), Tzintzuntzita (Block 70), and San Juan (Block 80), as well as the house caretakers who work for the owners of the weekend homes located along the lake shore (Block 60V).

SUMMARY – Data Analysis and Write-up

At this point, you have data (and certain measures about the data distribution) for Block 20, for each of five sections (barrios) of town, and for the entire community. Study the data that you have assembled and the corresponding statistics that you have generated. Look for intra-community variability -- i.e., patterns of similarities and differences. You should place the data and statistics into appendices. Illustrate your findings through the use of appropriate forms of data display -- i.e., graphs, charts, and tables. Your discussion of the findings should address the contemporary validity of the traditional Tzintzuntzan saying, “Here we are all equal,” which can be understood as a local way of stating the following null hypothesis (H₀): "there are no significant differences in standards of living among the households within the community of Tzintzuntzan." Your discussion should be no more than 4 pages (i.e., 1,000 words), although the supporting statistics, illustrations, and data sets will be considerably more substantial. Please make copies of the discussion only for all of your classmates.
