For instance, it can be used to determine the difference in means. A non-parametric test is less powerful than a parametric test thus the cost of carrying the test is cheaper. Non-parametric tests can be used to perform tests that cannot be carried out using parametric methods.
Sometimes it can be difficult to determine where a non-parametric or parametric test is appropriate especially where a normal distribution of data gives a continuous outcome. However, tests like Kolmogorov-Smirnov, Shapiro —Wilk, and Anderson-Darling can be conducted to determine whether parametric or non-parametric test is appropriate.
If the data follows a normal distribution, then a parametric test is warranted. If it does not follow a normal distribution, then a non-parametric test is conducted.
With non-parametric test being used widely today for various purposes, institutions continue issuing assignments from this area to make sure that students studying statistics understand the concepts completely.

If you are spending sleepless nights worrying about your non-parametric test assignments, we are here to help. Sampling is the method of selecting a representative sample from a large population and gathering data from the sample in order to understand certain aspects of the entire population. A population can be anything from a group of objects to a group of people you are studying.
Sampling is a time consuming, expensive, and complicated process, thus researchers have come up with various ways to carry out the process. The most widely used sampling methods today are random sampling and non-random sampling. In random sampling, the sample is drawn without any specific pattern and every individual in the population has an equal probability of being selected.
In non-random sampling, the probability of an individual being selected into a sample is usually greater than zero. Our statistics assignment help using SPSS includes sampling assignment help to assist students facing problems performing various sampling technics. We provide help in simple random sampling, equal probability systematic sampling, stratified simple random sampling, multistage stratified random sampling, cluster sampling, multistage cluster sampling, availability sampling, quota sampling, and expert sampling.
By seeking our help, you are not only going to comprehend each of these topics better but also improve your skills in conducting research. Inferential statistics enables you to make inferences or predictions from data.
This methodology allows you to take samples of a population and make general assumptions about the entire population. There are two main areas covered in inferential statistics namely, estimating parameters and hypothesis tests.
Estimating parameters involves taking certain data from the sample and using it to determine certain population parameters. Hypothesis tests are used to answer research questions from sample data.
With inferential statistics, sample data is taken from a small group of a population to determine if the test being performed works from every individual in the population. This technique is also used to compare samples of data to previous research or to other samples of data. It is valuable when a researcher is not able to examine each individual of an entire population. We provide the best SPSS statistics help to help you understand how to do your assignments by yourself next time and one that guarantees you excellent grades.
Our inferential statistics assignment help covers areas like binomial theorem, normal distributions, central limit theorem, t-distributions, confidence intervals, and comparison of means.
These are some of the areas that trouble students but we will guide you every step of the way. Hypothesis testing is the process of testing the results obtained from an experiment or survey to make sure that you have meaningful results.
Here, a set of data is compared against an idealized model that contains synthetic data. Technically, you will be testing the legitimacy of your results by assuming that your results might have happened by chance.
Hypothesis testing is one of the areas that students often get confused mainly because one has to determine the null hypothesis even before performing a hypothesis test. A null hypothesis is usually supported by facts.
To determine a null hypothesis, a student is presented with real-life situations and they are supposed to figure out what the hypothesis is from the problem. This can be tricky, as one will be looking at a fact that is not nullifiable.
Hypothesis testing assignments are difficult to handle and require one to have excellent skills in hypothesis testing. And since students want to have good grades in their SPSS assessment, they seek hypothesis testing homework help from experts.
We provide these services to help students perform better and achieve their academic goals. Descriptive statistics is used to describe the main features in the data of the samples being observed. Descriptive statistics is different from inferential statistics in that it describes what the data shows.
Inferential statistics makes conclusions that go beyond the data provided alone. For example, we use inferential statistics to find out what the entire population might think or describe what is going on with sample data. The most used types of descriptive statistics include mean, mode, median, standard deviation, skewness, and kurtosis.
These are used in almost all fields of maths and statistics to determine measures of variability and measures of central tendency. These two measures are presented in graphs, general discussions, and tables so that people can understand the meaning of data being evaluated.
A measure of central tendency describes the center position of the distribution of data being analyzed while a measure of variability studies how spread-out the distribution of data is.
Our SPSS experts provide students with descriptive statistics homework help to assist students complete assignments in this area. These professionals solve your assignments in a systematic manner explaining each step to make it easy for students to understand. Our company provides a one-stop solution to all your descriptive statistics assignment needs. We provide a material that is comprehensive enough to help you master the topics in question and assist you when revising for your exams.
Probability and statistics are branches of mathematics concerned with the collection and analysis of data. Probability is the study of chance that certain events will take place and is applied in our everyday lives. Statistics on the other hand is concerned with how data is collected, handled, and analyzed.
These two subjects go hand in hand and a student has to study one of them. This is topic gives the introduction to the principles and concepts of probability including the various terminologies used methods used to calculate probability. Our experts discuss concepts such as dependence and independence of events including the techniques of dealing with these concepts. This topic deals with the advanced concepts of probability like random variables, continuous and discrete probability distributions, as well as joint probability distributions.
This topic describes how hypothesis testing is used to analyze data and make relevant assumptions on expected results. The above topics are the basics of understanding the interaction between probability and statistics.
We hold your hand in these topics so that you do not face difficulties when dealing with projects assigned from these areas. If you are tired of getting poor grades in probability and statistics talk to us and we will help you achieve your dream goals. Regression is the method used to compare the value of variables against the values of other variables.
The variable being predicted is called the outcome variable or dependent variable and the variable used to predict the other is called the predictor variable or independent variable.
When analyzing data using regression, you need to make sure that the data being evaluated can actually be analyzed using regression. This is important, as your data needs to pass the six assumptions required for regression analysis to give you valid results. Below are the six assumptions used in regression:.
It is created for both non and interactive users. The package is developed for both non-interactive and interactive batch usages and can be managed with easy directions. Initially produced by SPSS it was purchased by IBM in and is commonly utilize by market scientists, health scientists, study business, federal government, education scientists, information miners and more.
