Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

There are two main types: one-way and two-way. Two-way tests can be with or without replication. One-way ANOVA between groups: used when you want to test two groups to see if there's a difference between them. Two way ANOVA without replication: used when you have one group and you're double-testing that same group.

Box and whisker plot: A tool used to display and analyze multiple sets of variation data on a single graph. Check sheet: A generic tool that can be adapted for a wide variety of purposes, the check sheet is a structured, prepared form for collecting and analyzing data. Control chart: A graph used to study how a process changes over time. Comparing current data to historical control limits leads to conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation). Design of experiments (DOE): A method for carrying out carefully planned experiments on a process. Usually, design of experiments involves a series of experiments that start by looking broadly at a great many variables and then focus on the few critical ones. Histogram: The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs. Scatter diagram: A diagram that graphs pairs of numerical data, one variable on each axis, to look for a relationship. Stratification: A technique that separates data gathered from a variety of sources so that patterns can be seen. Survey: Data collected from targeted groups of people about their opinions, behavior or knowledge.

An ANOVA test is a way to find out if survey or experiment results are significant. In other words, they help you to figure out if you need to reject the null hypothesis or accept the alternate hypothesis. Basically, you're testing groups to see if there's a difference between them.
