Filename: planetarium_attendance.xlsx Short description: The file 'planetarium_attendance.xlsx' lists planetariums which have purchased four fulldome shows "Black Holes: The Other Side of Infinity" (BH), "Dynamic Earth" (DE), "Solar Superstorms" (SS), and "Birth of Planet Earth" (BOPE)) as well as information about license length and high/low estimates for attendance, based on survey responses. 2. Relationship between files: NA 3. Additional related data collected that was not included in the current data package: NA 4. Are there multiple versions of the dataset? yes/no No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Combining existing datasets with survey data sent to planetariums. 2. Methods for processing the data: Planetariums were sent a survey to ask for data or estimates regarding attendance at shows. All survey questions were optional and allowed numerical or free-text answers to encourage the submission of partial information if available. Many planetariums provided rough, text-based answers e.g. “about 500 per year since the purchase date”), which were coded by two of the authors into a range of possible values. The coders followed a mutually agreed upon set of rules for coding, and met to discuss differences in interpretations. Where a consensus could not be reached among the coders, the lowest-low and highest-high were used for the range. We applied the following coding criteria with equations for hedge word estimation based on work from Ferson et al (Ferson et al 2015). 1. If an exact number is provided, use that value. 2. If an estimated number is provided, use the range x 2 * 10-d where d is the decimal place of the last significant digit of x. 3. If a phrase like “about x” is used, use the range x 2 *10-d. 4. If a phrase like “above x” is used, use the range [x, x+2 * 10-d]. 5. If the above calculations result in numbers that are negative or zero, reduce d by one. 6. If viewership information is not provided, calculate low and high estimates using numShowsPerWeek * numWeeksPerYear * numYearsSinceLicense * seatingCapacity * percentageSeatingCapacityUsed if these values are available. --numShowsPerWeek uses the reported survey value for the “high” estimate calculation and 1 for the “low” estimate calculation. We chose this range because upon cross-checking against their websites, it appeared several planetariums misunderstood the survey question “What is the number of showings for this show per week?” to mean all shows rather than the particular title. --numWeeksPerYear uses 49 (“low”) and 52 (“high”) weeks per year to account for planetarium closings. If the planetarium is part of a school district, the number of weeks in the school year is used. 7. Use the planetarium attendance and capacity information provided in the survey over information pulled from external databases. Use the numbers provided by respondents where possible. 8. If it is not possible to determine a number based on the response, mark the data for non-inclusion in the analysis. Each coder coded the data independently. There were 39 differences in interpretations prompting discussion. The most common issues (27 out of 39) were easy to resolve due to a simple misapplication of a rule or a coder not utilizing all relevant information, however several instances were difficult to resolve and required turning to outside sources of information. For example, one large planetarium claimed to have “63+” showings of Black Holes per week, adding that “Attendance is strong when BH is on the schedule”. This was an instance where the “63+” survey answer actually refers to the total number of shows played per week, and not specifically Black Holes shows. Our attempts to contact the planetarium to acquire scheduling information were unsuccessful, so per coding rule 6a, we initially coded a viewership range assuming the film is shown between 1 and 63 + 2 * 100 times per week, which resulted in a viewership estimate of 51,000 - 3,529,000 for this planetarium---an extraordinarily unhelpful range. Coder #2 identified historical versions of the planetarium’s website between 2012 - 2020 using The Internet Archive Wayback Machine, and from this was able to determine that the film was actually shown between 4 times a week 20% of the time, and 3 times a day 35% of the time. All coding differences were resolved after two days of discussions. 3. Instrument- or software-specific information needed to interpret the data: None, data is a human-readable spreadsheet. 4. Standards and calibration information, if appropriate: Coding of the qualitative data by two coders. 5. Environmental/experimental conditions: NA 6. Describe any quality-assurance procedures performed on the data: Coding of the qualitative data by two coders. 7.
