Statistics1 - Statistics Project ExampleThe calculated measure for model is called as statistic whereas the same measure for the population is known as parameter.Sampling misunderstanding is the error that occurs when the sample is not a representative of the population. This arises out of incorrect sampling method being used to describe the population. The error means that the statistic for the sample will be different from the parameter for the populationAn experiment is a scientific research method in which the researcher controls one or much variables and measures the changes in other variables. Experimental research is generally used when there is high degree of correlation between the variables.Dr. Jones has conducted an experimental study. Dr. Jones has controlled the variable quality of eat by dividing the sample into two groups and administering different quality of breakfast to each. Academic performance is the dependent variable which is studied for both the groups.Nom inal v/s Ordinal While nominal subdue is the representation of a descriptive category of the variable, the ordinal number scale is the representation of the also contains the magnitude of the order of the abide by on the scale. For example, while gender that contribute only have male or female as the value is a nominal scale, the position of a horse in a race is the example of the ordinal scaleOrdinal v/s Interval Apart from the ranking in an ordinal scale, the interval scale also the magnitude of the difference between two values in the series. For example temperature on days is an interval variable because we can also measure the magnitude of the difference between the temperatures on two days.Interval v/s ratio Apart from the measurement of magnitude, the ratio scale also contains the absolute zero value for a variable below which no value can exist. Example of such a variable will be
