Researchers collected data to examine the relationship between pollutants and preterm births in Southern California. During the study air pollution levels were measured by air quality monitoring stations. Specifically, levels of carbon monoxide were recorded in parts per million, nitrogen dioxide and ozone in parts per hundred million, and coarse particulate matter (PM\(_<10>\)) in \(\mu g/m^3\text<.>\) Length of gestation data were collected on 143,196 births between the years 1989 and 1993, and air pollution exposure during gestation was calculated for each birth. The analysis suggested that increased ambient PM\(_<10>\) and, to a lesser degree, CO concentrations may be associated with the occurrence of preterm births. 3 B. Ritz et al. « Effect of air pollution on preterm birth among children born in Southern California between 1989 and 1993 ». In: Epidemiology 11.5 (2000), pp. 502-511. Answer
(ii) Measurements of carbon monoxide, nitrogen dioxide, ozone, and particulate matter less than 10\(\mu g/m^3\) (PM\(_<10>\)) collected at air-quality-monitoring stations as well as length of gestation. These are continuous numerical variables.
(ii) Brand new variables was basically whether or not the patient skilled the Buteyko means (categorical) and you can tips out-of standard of living, interest, asthma symptoms and medication reduction of the fresh customers (categorical, ordinal). Additionally, it may end up being reasonable to relieve the critiques on the an excellent measure of just one so you can ten because distinct numerical details.
