What is a regression line? A regression line is a straight line used in linear regression to indicate a linear relationship between one independent variable (on the x-axis) and one dependent variable (on the y-axis). Regression lines may be used to predict the value of Y for a given value of X.
Predictive Analysis:Predictive Analysis is used to determine what is likely to occur in the future based on data patterns from the past. Inferential analysis:Draw conclusions, predict, or test findings about a population based on a representative sample of data. We use it to draw inferences about...

In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25 percent of data points, where the...
Apply grouping: Using the defined attributes, implement the groupby() function in a programming language, like pandas or SQL, to organize the data. Perform calculations: carry out statistical computations like mean, sum, count, and standard deviation on each group of data. Pivot the data: Use...
The mathematical representation is as follows Z = (X - m ) / s where X?a data point m?the mean s?the standard deviation Z?the standardized value Algorithm Step 1? Import the libraries required. Some of the commonly imported libraries to standardize an ML model are numpy, pandas or sciki...
Standard deviation is a measure of the dispersion and/or variation in data. It tells us how to spread out the returns around their mean. To calculate SD, subtract each value in a data set from its mean, squaring the value, average all squared values, and finally take the square root of...
We will become familiar with the equations for computing the variance and standard deviation of datasets as well as figuring out percentiles and quartiles. Furthermore, we will envision those factual measures with visualization. We will use tools such as box plots to gain knowledge from statistics...
