Some formulas statisticians may use are population mean, sample mean, variance, and standard deviation. They may also use linear regression line and standard error equations. Another can be the mean value of a data set, where one adds all data points given in a set and divides this number by the number of data points in the set.

Who discovered the sample size calculation formula?
The concept of sample size calculation has evolved over time, with contributions from various statisticians. However, key developments in the formula for sample size calculation can be attributed to statisticians like Jerzy Neyman and Egon Pearson in the 20th century, who formalized concepts related to hypothesis testing and estimation. Their work laid the foundation for modern statistical methods, including sample size determination.
Graphs and intercepts in the real world?
businesses would use them to predict trends in data and statisticians would use them to extrapolate the results of a sample group of a study or survey.
How do statisticians use algebra?
One example is linear transformations, which are a key element of statistics. The fact that a linear transform of a Normal variabe is also a normal variable is central to the use of z-scores for calculating normal probabilities and so for hypothesis testing.

How do statisticians use math?
Statisticians use math to analyze and interpret data, make predictions, test hypotheses, and draw conclusions about the relationships between variables. They apply mathematical techniques like probability theory, calculus, and linear algebra to design experiments, develop models, and uncover patterns in data. Math is essential for statisticians to understand and communicate the significance and reliability of their findings.
