Which is better physics or statistics?

Both subjects require you to analyse carefully, and think out of the box. But Unlike physics or pure mathematics, statistics has a greater degree of freedom from formulae and It requires more rapid use of IQ than physics. Though it totally depends on the person which subject he finds easier but for me it's physics.

About This Chapter

If you need help preparing for a test that covers basic statistics, you've reached the right place! In this chapter are fun lessons and mini quizzes you can use to strengthen your statistics knowledge and ensure you're ready to answer questions on exam day.

1. Mean, Median & Mode: Measures of Central Tendency

In research, measures of central tendency are descriptive statistics that help researchers understand which data is more representative of a data set. Explore the mean, median, and mode. Understand how each measure is calculated, and learn how researchers use each measure to understand samples, as well as the populations that samples represent.

2. What is Standard Deviation? - Definition, Equation & Sample

Standard deviation is a statistical measure that indicates how far or how close the values in a data set are from the mean. Examine the definition of standard deviation and variance, learn the equation for standard deviation, and follow an example to find a sample's standard deviation.

3. Frequency Distributions: Definition & Types

A frequency distribution is a list of numerical figures represented in a table diagram or histogram that detail how often each value occurs in a set of data. Learn about definition and types of frequency distributions.

4. Interpreting Quantitative & Qualitative Business Data

Both qualitative and quantitative data can be analyzed and interpreted to guide business decisions. See how these two analyses can be used, and how to interpret each of their results to inform business decisions.

How are probability distributions used in statistics?from classcentral.com

Probability distributions form the core of many statistical calculations. They are used as mathematical models to represent some random phenomenon and subsequently answer statistical questions about that phenomenon. This module starts by explaining the basic properties of a probability distribution, highlighting how it quantifies a random variable and also pointing out how it differs between discrete and continuous random variables. Subsequently the cumulative probability distribution is introduced and its properties and usage are explained as well. In a next lecture it is shown how a random variable with its associated probability distribution can be characterized by statistics like a mean and variance, just like observational data. The effects of changing random variables by multiplication or addition on these statistics are explained as well.The lecture thereafter introduces the normal distribution, starting by explaining its functional form and some general properties. Next, the basic usage of the normal distribution to calculate probabilities is explained. And in a final lecture the binomial distribution, an important probability distribution for discrete data, is introduced and further explained. By the end of this module you have covered quite some ground and have a solid basis to answer the most frequently encountered statistical questions. Importantly, the fundamental knowledge about probability distributions that is presented here will also provide a solid basis to learn about inferential statistics in the next modules.

What is descriptive statistics?from classcentral.com

Methods for summarizing sample data are called descriptive statistics. However, in most studies we’re not interested in samples, but in underlying populations. If we employ data obtained from a sample to draw conclusions about a wider population, we are using methods of inferential statistics. It is therefore of essential importance that you know how you should draw samples. In this module we’ll pay attention to good sampling methods as well as some poor practices. To draw conclusions about the population a sample is from, researchers make use of a probability distribution that is very important in the world of statistics: the sampling distribution. We’ll discuss sampling distributions in great detail and compare them to data distributions and population distributions. We’ll look at the sampling distribution of the sample mean and the sampling distribution of the sample proportion.

How is statistics taught?from en.wikipedia.org

First, statistics is often taught as part of the mathematics curriculum, by instructors trained in mathematics and working in a mathematics department . Second, statistical theory has often been taught as a mathematical theory rather than as the practical logic of science --- as the science that "puts chance to work" in Rao's phrase--- and this has entailed an emphasis on formal and manipulative training, such as solving combinatorial problems involving red and green jelly beans. Statisticians have complained that mathematicians are prone to over-emphasize mathematical manipulations and probability theory and under-emphasize questions of experimentation, survey methodology, exploratory data analysis, and statistical inference.

How does statistics help in research?from real-statistics.com

Statistics plays a central role in research in the social sciences, pure sciences and medicine.

Values may be evenly distributed along a bell curve, suggesting the data represent the normal range of naturally occurring phenomena, or be erratic, suggesting no underlying factors behind the values.

What is multiple linear regression?

Multiple linear regression may be used to nd the re-lationship between a single, continuous outcome vari-able and a set of predictor variables that might becontinuous , dichotomous, or categorical; if categori-cal, the predictors must be recoded into a set of di-chotomous dummy variablesMultiple linear regression, in which two or more in-dependent variables (predictors) are related to a sin-gle dependent variables is much more common thansimple linear regression. Two general principles ap-ply to regression modelling. First, each variable in-cluded in the model should carry its own weight, itshould explain unique variance in the outcome vari-able. Second, when you deal with multiple predictors,you have to expect that some of them will be corre-lated with one another as well as with the dependentvariable.
