02/22/2024 | By: FDS

The statistical toolkit includes fundamental tools and concepts used in statistical analysis. Here are some key elements of the statistical toolkit:

1. Descriptive Statistics

Mean: Average values of a data set.

Median: The middle value in a sorted data set.

Standard Deviation: Measure of the spread of values around the mean.

2. Inferential Statistics

Significance Level: Threshold to determine the significance of results.

Confidence Interval: Interval for possible values of a parameter with a certain probability.

p-Value: Probability that the observed data is random when the null hypothesis is true.

3. Correlation Diagnosis

Correlation Coefficient: Measure of the strength and direction of the relationship between two variables.

Scatter Plot: Graphic representation of data points in a coordinate system.

4. Regression

Regression Analysis: Modeling the relationship between dependent and independent variables.

Residual Analysis: Checking the deviations between observed and predicted values.

Understanding and applying this statistical toolkit are crucial for meaningful data analysis and interpretation of results.
