The intuitive idea behind the bootstrap is this: if your original dataset was a random draw from the full population, then if you take subsample from the sample (with replacement), then that too represents a draw from the full population. You can then estimate your model on all of those bootstrapped datasets.
IBM SPSS Bootstrapping Overview United States
Bootstrapping is any test or metric that uses random sampling with replacement (e.g. mimicking the sampling process), and falls under the broader class of resampling methods. Bootstrapping assigns measures of accuracy ( bias, variance, confidence intervals, prediction error, etc.) to sample estimates.

Bootstrapping is a resampling technique that provides information otherwise unavailable if we fit our model only once on the original sample. While we may be familiar with the ' what ' and ' how ' behind bootstrapping, this article aims to present the ' why ' of bootstrapping in a layman manner.
Bootstrapping in SPSS Part 3 YouTube
Bootstrapping. Bootstrapping is a method for deriving robust estimates of standard errors and confidence intervals for estimates such as the mean, median, proportion, odds ratio, correlation coeficient or regression coefficient. It may also be used for constructing hypothesis tests.
Interpreting bootstrap results in SPSS (V24 and earlier) YouTube
Bootstrapping is a statistical technique that falls under the broader heading of resampling. This technique involves a relatively simple procedure but repeated so many times that it is heavily dependent upon computer calculations. Bootstrapping provides a method other than confidence intervals to estimate a population parameter.
Bootstrapping in SPSS Part 2 YouTube
Bootstrapping is a method for deriving robust estimates of standard errors and confidence intervals for estimates such as the mean, median, proportion, odds ratio, correlation coefficient or regression coefficient. It may also be used for constructing hypothesis tests.
One way ANOVA with Bootstrapping in SPSS YouTube
Introduction to bootstrapping When collecting data, you are often interested in the properties of the population from which you took the sample. You make inferences about these population parameters with estimates computed from the sample.
IBM SPSS Bootstrapping Demo YouTube
How Bootstrapping Works At its simplest, for a dataset with a sample size of N, you take B "bootstrap" samples of size N with replacement from the original dataset and compute the estimator for each of these B bootstrap samples. These B bootstrap estimates are a sample of size B from which you can make inferences about the estimator.

IBM SPSS Bootstrapping Überblick Deutschland
"Bootstrapping is a statistical procedure that resamples a single dataset to create many simulated samples. This process allows for the calculation of standard errors, confidence intervals, and hypothesis testing" ( Forst).
Multiple regression with bootstrapping in SPSS YouTube
IBM SPSS Bootstrapping helps reduce the impact of outliers and anomalies that can degrade the accuracy or applicability of your analysis. As a result, you have a clearer view of your data for creating the model you are working with. Fast, easy re-sampling -- estimate the sampling distribution of an estimator in a snap.

IBM SPSS Statistics 25 has a powerful feature known as Bootstrapping.This is a feature that people who are performing more advanced statistical analysis may need. The feature is included in the IBM SPSS Statistics 25 Student Grad Pack Premium and the Premium Faculty Pack.However, there is a known issue with the bootstrapping option that may prevent you from being able to use the feature.

The bootstrap is, by far, the most prevalent method for validating statistical findings. Random samples (1000's of them, if you want) of your dataset are taken, statistical analyses are run on each random sample, and a 95% bootstrap confidence interval for the primary finding is generated.
