2. Correlation: This function calculates the correlation coefficient between two variables, helping users understand the strength and direction of the relationship between them.
3. Regression Analysis: This tool allows users to perform linear regression analysis to predict the value of a dependent variable based on one or more independent variables. This is vital for forecasting and trend analysis.
4. ANOVA (Analysis of Variance): ANOVA is used to compare means across multiple groups to determine if any significant differences exist.
5. t-Test: This statistical test is used to determine if there is a significant difference between the means of two groups, which can be useful for hypothesis testing.
6. F-Test: This tool assesses whether two population variances are equal, which is important in various statistical analyses.
7. Histogram: The histogram tool helps users visualize the distribution of data points across specified intervals, providing insights into data patterns.
8. Exponential Smoothing: This technique is used for time-series forecasting, allowing users to smooth out data trends over time.
