Making Inferences from Data Introduction Managing Data. 2019-10-30 · Interestingly, these inferential methods can produce similar summary values as descriptive statistics, such as the mean and standard deviation. However, as I’ll show you, we use them very differently when making inferences. Hypothesis tests. Hypothesis tests use sample data answer questions like the following:, We make estimates about the population through the use of the sample data. Estimates can either be point estimates or interval estimates. Xbar is an estimator of μ and s (sample standard deviation) is an estimator of σ. We call the specific value of an estimator the estimate (e.g., 3.5 cm is our estimate of the population mean (μ))..

For instance, we use inferential statistics to try to infer from the sample data what the population might think.
