Quartile: A quartile is a statistic that divides a data set into four equal parts. The first quartile is the lowest 25% of the data, the second quartile is the lower 50% of the data, the third quartile is the upper 50% of the data, and the fourth quartile is the highest 25% of the data.
Definition of Quantitative Quantitative: Quantitative means numerical. Quantitative data is data that can be measured or counted. Quantitative refers to the use of numbers and mathematical models to understand and analyze data. It is a branch of statistics that deals with the measurement, analysis, interpretation, presentation, and organization of data.
Definition of Null Hypothesis The null hypothesis is a statement that is presumed to be true until evidence is presented to suggest otherwise. In statistics, the null hypothesis is typically contrasted with the alternative hypothesis, which is the statement that is posited if the null hypothesis is found to be false. The null hypothesis is…
Bivariate Analysis is the examination of two sets of data, typically in order to identify any correlations between them. This can be used to inform further analysis, or to gain a better understanding of the data…
Definition of Normalized Normalized: Normalized is a statistic term referring to the process of adjusting a value to have a unit of measurement. For example, the value of weight can be normalized by dividing it by the unit of weight, such as kilograms.
Definition of Data Frame Data Frame: A data frame is a rectangular table of data consisting of rows and columns. The data in each column has the same type, and the order of the columns is defined by the programmer. What is a Data Frame used for? A data frame is a two-dimensional data structure…
Definition of Mathematical Statistics Mathematical Statistics: Mathematical statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It also provides techniques for estimating properties of populations from samples. Mathematical statistics is distinguished from other statistical techniques in that it relies on mathematical theory as a foundation. What…
