Use
Bootstrapping
for 1-sample function to explore the sampling distribution of a specified statistic of a sample of data and to estimate a confidence interval for the population parameter. You can also use
Bootstrapping
for 1-sample function to illustrate important statistical concepts. You can choose from the following statistics:
- Mean
- Proportion
- Median
- Sum
- Variance
- Standard deviation
For example, an environmental scientist wants to estimate the median amount of calcium in water from the wells in a geographical region. The scientist uses a bootstrap for the median to examine the sampling distribution of the median and to estimate a confidence interval for the median amount of calcium in the water.
- The confidence interval provides a range of likely values for the population median.
- The histogram shows the variation and shape of the sampling distribution.
- Resampling techniques can show the effect of sample size on the sampling distribution.
