WebbTwo very different distributions of responses to a 5-point rating scale can yield the same mean. Consider the following example showing response values for two different ratings. In the first example (Rating "A") the Standard Deviation is zero because ALL responses were exactly the mean value.

Webb6 jan. 2024 · Examples Of Type I Error Let’s take an example of the trail of a condemned criminal. The null hypothesis can be considered as an innocent person, while others treat it as guilty. In this case, Type I error means that the individual is not found to be innocent. And individual needs to be sent to jail, despite being an innocent.
WebbIn statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent … ctoo meaningWebbA: Answer: From the given data, Sample size (n) = 250 Sample mean x¯ = 2.5 Standard deviation (s) = 0.2… Q: A regional planner obtains random samples of home costs from four Michigan counties.
