  • Excerpt: Data on 816 brands of cigarettes. What relationships are there among the nicotine content, tars, and CO? Are any brands unusually high or low in nicotine? Can you account for that?

  • Climate_change_2016 Download .TXT file Open in Data Desk ?
  • Methods: Multiple Regression, Regression
  • Source: Global temperature fromhttps://www.ncdc.noaa.gov/cag/data-info/global Global temperature anomaly data come from the Global Historical Climatology Network-Monthly (GHCN-M) data set and International Comprehensive Ocean-Atmosphere Data Set (ICOADS), which have data from 1880 to the present. These two datasets are blended into a single product to produce the combined global land and ocean temperature anomalies. The available timeseries of global-scale temperature anomalies are calculated with respect to the 20th century average, while the mapping tool displays global-scale temperature anomalies with respect to the 1981-2010 base period. For more information on these anomalies, please visit Global Surface Temperature Anomalies.

  • Number of Cases: 58
  • Excerpt: Scientists claim that changes in the mean global temperature are primarily due to changes in CO2 levels. Both trends are here from 1959 to 2016. For an alternative, the data includes the annual closing price of the Dow Jones Industrial Average. Can it predict global temperature?

  • Number of Cases: 756
  • Excerpt: Climate scientists are concerned about the increase in carbon dioxide (CO2) levels in the atmosphere because CO2 is a greenhouse gas, trapping heat from sunlight. One of the best time series measuring CO2 levels is recorded monthly on the top of Mauna Loa in Hawaii. Because it is in the middle of the Pacific, the […]
