HYPOTHESIS TESTING#1

A statistical method used to determine if there is enough evidence to reject a null hypothesis, based on sample data.

ANOVA#2

Analysis of Variance; a technique used to compare means among three or more groups to assess if at least one group mean is different.

MANOVA#3

Multivariate Analysis of Variance; an extension of ANOVA that assesses multiple dependent variables simultaneously.

MULTIVARIATE ANALYSIS#4

Statistical techniques used to analyze data that involves multiple variables, helping to understand relationships and effects.

p-VALUE#5

A measure that helps determine the significance of results in hypothesis testing; a lower p-value indicates stronger evidence against the null hypothesis.

TYPE I ERROR#6

The incorrect rejection of a true null hypothesis; also known as a false positive.

TYPE II ERROR#7

The failure to reject a false null hypothesis; also known as a false negative.

REGRESSION ANALYSIS#8

A statistical method for modeling the relationship between a dependent variable and one or more independent variables.

COEFFICIENT OF DETERMINATION#9

Also known as R-squared; it indicates the proportion of variance in the dependent variable explained by the independent variables.

MODEL DIAGNOSTICS#10

Techniques used to assess the validity and fit of a statistical model, ensuring accurate interpretations.

DATA INTERPRETATION#11

The process of making sense of numerical data, identifying trends, and drawing conclusions based on statistical analyses.

VISUALIZATION#12

The graphical representation of data to help communicate findings clearly and effectively to diverse audiences.

EXECUTIVE SUMMARY#13

A concise overview of a report's key findings and recommendations, aimed at decision-makers.

STATISTICAL SIGNIFICANCE#14

A determination that the observed results are unlikely to have occurred by chance, typically assessed using p-values.

MULTIVARIATE REGRESSION#15

A regression analysis technique that models relationships between one dependent variable and multiple independent variables.

DATA SET#16

A collection of data points organized for analysis, which can include various types of variables.

CATEGORICAL VARIABLE#17

A variable that can take on one of a limited, fixed number of possible values, representing different categories.

CONTINUOUS VARIABLE#18

A variable that can take an infinite number of values within a given range, often measured on a scale.

SAMPLE SIZE#19

The number of observations or data points collected for analysis; larger sizes generally yield more reliable results.

CONFIDENCE INTERVAL#20

A range of values that is likely to contain the true population parameter, reflecting the uncertainty of an estimate.

OUTLIER#21

A data point that differs significantly from other observations, potentially indicating variability or error.

DATA CLEANING#22

The process of identifying and correcting inaccuracies or inconsistencies in data to ensure quality analysis.

STATISTICAL SOFTWARE#23

Tools and applications used for conducting statistical analyses, such as R, SPSS, or Python libraries.

RESULTS PRESENTATION#24

The practice of conveying statistical findings in a clear, engaging manner, tailored to the audience's level of understanding.

FEEDBACK LOOP#25

A process in which outputs of a system are circled back and used as inputs, enhancing learning and improvement.
