{"part":"task","text":"# Datasets\nPass a dataset's id as the `dataset` argument.\n{\n \"id\": \"minwage\",\n \"rows\": 358,\n \"description\": \"Two social science researchers examined the impact of raising the minimum wage on employment in the fast-food industry. In 1992, the state of New Jersey (NJ) in the United States raised the minimum wage from $4.25 to $5.05 per hour. Did such an increase in the minimum wage reduce employment as economic theory predicts? As discussed above, answering this question requires inference about the NJ employment rate in the absence of such a raise in the minimum wage. Since this counterfactual outcome is not observable, we must somehow estimate it using observed data.\\nOne possible strategy is to look at another state in which the minimum wage did not increase. For example, the researchers of this study chose the neighboring state, Pennsylvania (PA), on the grounds that NJ\u2019s economy resembles that of Pennsylvania, and hence the fast-food restaurants in the two states are comparable. Under this cross-section comparison design, therefore, the fast-food restaurants in NJ serve as the treatment group receiving the treatment (i.e., the increase in the minimum wage), whereas those in PA represent the control group, which did not receive such a treatment. To collect pretreatment and outcome measures, the researchers surveyed the fast-food restaurants before and after the minimum wage increase. Specifically, they gathered information about the number of full-time employees, the number of part-time employees, and their hourly wages, for each restaurant.\\n\\nThe CSV file minwage.csv contains this data set.\\nVariable Description\\nchain: name of the fast-food restaurant chain\\nlocation: location of the restaurants (centralNJ, northNJ, PA, shoreNJ, southNJ)\\nwageBefore: wage before the minimum-wage increase\\nwageAfter: wage after the minimum-wage increase\\nfullBefore: number of full-time employees before the minimum-wage increase\\nfullAfter: number of full-time employees after the minimum-wage increase\\npartBefore: number of part-time employees before the minimum-wage increase\\npartAfter: number of part-time employees after the minimum-wage increase\",\n \"columns\": {\n  \"chain\": \"str\",\n  \"location\": \"str\",\n  \"wageBefore\": \"float64\",\n  \"wageAfter\": \"float64\",\n  \"fullBefore\": \"float64\",\n  \"fullAfter\": \"float64\",\n  \"partBefore\": \"float64\",\n  \"partAfter\": \"float64\"\n }\n}"}
