Child Miners in Cajamarca, Peru,The frequency tables you prepared in Chapter 4 provide summaries of your data files. Because it is even easier to look at a picture than to read a table, you generally will want to draw a . to represent a frequency table pictorially.词汇 发表于 2025-3-23 15:58:08
https://doi.org/10.1007/0-306-48059-XMany data sets in exploration geochemistry contain variables that are distributed lognormally, meaning that the logarithms of the observations rather than the observations themselves follow a normal distribution more or less closely. Indeed, for many data sets all of the geochemical variables may be distributed lognormally.亚麻制品 发表于 2025-3-23 21:47:11
Hazardous Waste Legislation /Organization,We often want to compare a pair of variables to learn if they plot on an approximately straight line or, in other words, if they are related through a simple linear regression. The method is explained in .;. you will also find an explanation in standard statistical textbooks.被诅咒的人 发表于 2025-3-24 02:01:04
Qindii Shafi,Ali Elkamel,Zarook ShareefdeenPlotting data is essential for recognizing patterns and relationships among variables. A plot also will help you identify unusual values that may be anomalous or that may be mistakes.archetype 发表于 2025-3-24 02:57:53
