                 Formulas in statistics have been very benefitable to researches and daily life. One kind of it is measures of central tendency. They can help us to get portray of how data is distributed within researches. Besides, these things help us to make market research for companies, like mode. It can be interpreted as trends in marketing, either in traditional or digital marketplace. While median is used as a benchmark of judgement of GPA rank in schools and colleges. This formula is needed when a college admission committee want to select students to enter the higher education programs. Mean, as we know, used to measure ability of teacher's success in educate his or her students. Too, it is used to measure a student understanding of lessons in student report. Quartile equation can be used to determine research journal quality.

                   Two new formulas are made when I do this research with my friends. The new mode formulas I mean here are presented below. First formula is like this, used for finding value of mode class that have odd interval:

With:

Mo = Mode

k₁ = Frequency variance of precede class and mode class

k₂ = Frequency variance of mode class and next class

                       Whilst for the even one, we can count with this:

With:

n = 2k₂ - 1

                     Formula above can only be used for mode which the class interval is located in number that is more than 50. For mode which the class interval is located in number that is less than 50, we need to apply this mathematical statement.

With:

n = 2k₁ - 1

                       That's all we can discuss. I hope this content is always having benefits for all of us. If you have any questions, please comment below. Thank you for visiting my blog!
