  A Deep Dive into One Sample t-Test Using Agri Analyze: Tutorial and Example (10 min) The blog is about concept of one sample t test, formula, interpretation, solved example and demonstration in Agri Analyze tool 1. Introduction The one-sample t-test is a statistical method used to determine if the mean of a single sample is significantly different from a known or hypothesized population mean. It is widely used in various fields to test hypotheses about population means when the population standard deviation is unknown and the sample size is relatively small. 2. When to Use a One-Sample T-Test You should use a one-sample t-test when you want to compare the mean of a sample to a specific value, typically a known population mean or a hypothesized value. This test is particularly useful when: You have a single sample of data. The population standard deviation is unknown. The sample size is small (usually n < 30). 3. Assumptions of a One-Sample T-Test For the one-sample t-test to b...

 The Blog is about CRD analysis theory, example and analysis using Agri Analyze tool Link of the MCQ for CRD design is shared in bottom Introduction Experimental design in agriculture is a systematic approach to planning and conducting field experiments. It involves designing the layout of experimental plots, allocating treatments and randomizing treatments to minimize bias. Common designs include Completely Randomized Design (CRD), Randomized Complete Block Design (RCBD), Factorial design, Split-plot design, and Latin square design. These designs help evaluate the effects of different factors on crops, soils, pests and other agricultural outcomes. By providing reliable and reproducible results, experimental design guides farmers and policymakers in making informed decisions to improve agricultural practices. 1.              What is Completely Randomized Design (CRD)?         ...
