24-hour mean indoor fine particulate matter concentrations across subcategories of 20 Western Montana residences during the 2022 wildfire season

m2 = square meters; C = degrees Celsius; $75k = 75 thousand United States Dollars

Outdoor temperature categorized by median daily outdoor temperature measured by PurpleAir sensors over the duration of the study (24 C).

The lower and upper hinges correspond to the first and third quartiles (the 25th and 75th percentiles). The upper whisker extends from the hinge to the largest value no further than 1.5 * IQR from the hinge (where IQR is the interquartile range, or distance between the first and third quartiles). The lower whisker extends from the hinge to the smallest value at most 1.5 * IQR of the hinge. Data beyond the end of the whiskers are called “outlying” points and are plotted individually.
