Step by Step Process of How to Solve Statistics Problems
WebStatics Problems. On this page I put together a collection of statics problems to help you understand static equilibrium better. The required equations and background reading to solve these problems is given on the equilibrium page . Problem # 1. A ball of mass 10 kg is hanging vertically from a string. What is the tension in the string? WebCalculation of median of raw data: (i) If the number of observations ‘ n ’ is odd, then the median will be the value of observation. (ii) If n is even, then we have two middle terms i.e. (n/2) th observation and (n/2 + 1) th observation. Median of the given data will be mean of these two middle observations. crystal lockey

WebA statistics problem typically contains four components: 1. Ask a Question. Asking a question gets the process started. It’s important to ask a question carefully, with an understanding of the data you will use to find your answer. 2, Collect Data. Collecting data to help answer the question is an important step in the process. WebTherefore, the paired samples t-test is an appropriate statistical test to use in this case because the two samples are related, and the goal is to determine if there is a significant difference between the means of the two related samples. 2. I don't have access to specific datasets in SPSS. WebApr 10, 2024 · Based on these plots, we should. A) Transform the data by taking logs. B) Difference the series to obtain stationary data. C) Fit an MA (1) model to the time series. Solution: (B) The autocorr shows a definite trend and partial autocorrelation shows a choppy trend, in such a scenario taking a log would be of no use. crystal locklear
