PPT-Lecture-2: Ask question and create hypothesis

Steps of the scientific method The scientific method uses a series of steps to establish facts or create knowledge The overall process is well established but the specifics of each step may change depending on what is being examined and who is performing it . Nature of Science. Nature of Science . – . Scientific should be . reliable. and always . changing. Science is complex . No step-by-step method will always be the answer to a question. science relies on skills: . MatLab. Lecture 23:. Hypothesis Testing continued; F-Tests. . Lecture 01. . Using . MatLab. Lecture 02 Looking At Data. Lecture 03. . Probability and Measurement Error. . Lecture 04 Multivariate Distributions. Safety. Handle termites in a humane manner.. Purpose. To think as a scientist thinks by. Asking questions. Gathering information . Making observations. Using logical reasoning. Creating predictions and explanations. How does a hypothesis begin?. What do you do with it?. How do you make one?. How does a hypothesis begin?. Scientists make lots of observations. This leads them to form scientific questions about what they have observed. Each scientist creates an explanation – or hypothesis – that he or she thinks will answer the question.. Textbook: . Sections 12.1 to 12.4. • Formulate null and alternative hypotheses correctly based on the context of a testing situation.. • Distinguish between a one-sided and two-sided alternative hypothesis.. Can I create an experiment to find the answer?. Does it provide data to be measured?. Is it answered with a yes or no?. Which gum makes the biggest bubble?. Which gum is the most expensive?. How does an eye work?. Writing a Hypothesis. Quick Questions. What do we remember about testable questions?. What is a hypothesis?. What do hypotheses have in common with testable questions?. How do we write a hypothesis?. (1-Sample). STEP 1, Null and Alternate Hypotheses. State the. “Null Hypothesis”. and . “Alternate Hypothesis”. STEP 1, Null and Alternate . Hypotheses.

Each person will write down their answers to the questions on their paper. At the end, you will trade papers with a neighbor and grade the answers. Then, you will calculate the average score for your table. Alison K. Hall, PhD. Associate Dean, Research Workforce Development. November 12, 2019. Framing the Question. Research begins with a question, . that leads to a hypothesis . that leads to aims and approach. What affects hypothesis testing? . Taking this class has made you intellectually curious (I’m serious!). So, you decide to see whether Edison light bulbs last as long as the package says they do; according to the package: µ = 1200 .
