The formula for the interquartile range is IQR = Q 3 - Q 1. Both the range and interquartile range are limited by the fact that they only use two values from the entire dataset. The variance is a measure of variability that uses all data values. Sample Variance. Population Variance. s 2 = ∑ ( x − x ¯) 2 n − 1.Consider statistics as a problem-solving process and examine its four components: asking questions, collecting appropriate data, analyzing the data, and interpreting the results. This session investigates the nature of data and its potential sources of variation. Variables, bias, and random sampling are introduced. View Transcript.Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

Wolfram|Alpha can compute expert-level solutions for various statistics topics, such as elementary math, algebra, calculus, geometry, differential equations, and more. It uses Wolfram's algorithms, knowledgebase and AI technology to provide answers for math, science, society, everyday life and more. Solution: Depending on what your distribution represents, start by either writing the formula for the z-score of a population: z = x−μ σ z = x − μ σ. or the formula for the z-score of a sample: z = x− ¯x s z = x − x ¯ s. Substitute in values for this problem (data value, mean, and standard deviation) into the formula: z = 106− ...Step 6: Subtract 1 from the sample size to get the degrees of freedom. We have 11 items. So 11 – 1 = 10. Step 7: Find the p-value in the t-table, using the degrees of freedom in Step 6. But if you don’t have a specified alpha level, use 0.05 (5%).. So for this example t test problem, with df = 10, the t-value is 2.228. Hypothesis Testing Calculator. The first step in hypothesis testing is to calculate the test statistic. The formula for the test statistic depends on whether the population standard deviation (σ) is known or unknown. If σ is known, our hypothesis test is known as a z test and we use the z distribution. If σ is unknown, our hypothesis test is ... Free Probability Problems Calculator - solve probability word problems step by step
