False precision (also called overprecision, fake precision, misplaced precision, and spurious precision) occurs when numerical data are presented in a manner that implies better precision than is justified; since precision is a limit to accuracy (in the ISO definition of accuracy), this often leads to overconfidence in the accuracy, named precision bias.
One usable definition is: "Misuse of Statistics: Using numbers in such a manner that – either by intent or through ignorance or carelessness – the conclusions are unjustified or incorrect." [1] The "numbers" include misleading graphics discussed in other sources. The term is not commonly encountered in statistics texts and there is no ...
An example of the modifiable areal unit problem and the distortion of rate calculations. The modifiable areal unit problem (MAUP) is a source of statistical bias that can significantly impact the results of statistical hypothesis tests.
In statistics, a misleading graph, also known as a distorted graph, is a graph that misrepresents data, constituting a misuse of statistics and with the result that an incorrect conclusion may be derived from it. Graphs may be misleading by being excessively complex or poorly constructed.
Most investors heaved a sigh of relief when the nation's gross domestic product, a broad measure of economic activity, rose 3.5% in the third quarter, signaling that the recession had ended. But ...
Simpson's paradox has been used to illustrate the kind of misleading results that the misuse of statistics can generate. [ 7 ] [ 8 ] Edward H. Simpson first described this phenomenon in a technical paper in 1951, [ 9 ] but the statisticians Karl Pearson (in 1899 [ 10 ] ) and Udny Yule (in 1903 [ 11 ] ) had mentioned similar effects earlier.
While precision is a description of random errors (a measure of statistical variability), accuracy has two different definitions: More commonly, a description of systematic errors (a measure of statistical bias of a given measure of central tendency, such as the mean). In this definition of "accuracy", the concept is independent of "precision ...
A steady stream of false and misleading information is circulating online around the 2024 election. Two videos circulating on social media on Wednesday are falsely claiming they show wrongdoing around voting in Pennsylvania, a key swing state. Officials provided details on what is actually shown in the videos. Here’s a look at the facts.
