pH is a measure of the acidity or alkalinity of a solution on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• It measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9

The potential of hydrogen (pH) scale measures the acidity or alkalinity of a substance on a scale of 0 to 14.

• pH values below 7 indicate acidity, with 0 being the most acidic

• pH values above 7 indicate alkalinity, with 14 being the most alkaline

• A pH of 7 is considered neutral, such as pure water

• pH is important in various industries like agriculture, food production, and water treatment

Different types of Time Series include trend, seasonality, cyclic, and irregular components.

• Trend: Long-term increase or decrease in data over time.

• Seasonality: Repeating patterns or cycles at regular intervals.

• Cyclic: Fluctuations that are not of fixed period.

• Irregular: Random variations in data that cannot be attributed to trend, seasonality, or cyclic patterns.

Time series is used when data points are collected over time and have a sequential order, while regression is used for predicting continuous outcomes based on independent variables.

• Time series is used when analyzing data points collected at regular intervals over time.

• Regression models are used when predicting continuous outcomes based on independent variables.

• Time series can capture trends, seasonality, and cyclic pat...read more
