Inferential statistics is one of the two statistical methods employed to analyze data, along with descriptive statistics. The goal of this tool is to provide measurements that can describe the overall population
Inferential statistics is strongly associated with the logic of hypothesis testing. A hypothesis is an empirically verifiable declarative statement concerning the relationship between independent and dependent variables and their corresponding measures. In hypothesis testing, main aim is usually to reject the...
In the field of business statistics, there are two types of business statistics. First, there isdifferential statistics, which primarily deals with monitoring changes and trends over time. On the other hand, we haveinferential statistics, a valuable tool for drawing insights about an entire populati...
A t-test is an inferentialstatisticused to determine if there is a significant difference between the means of two groups and how they are related. T-tests are used when the data sets follow a normal distribution and have unknown variances, like the data set...
In addition, the statistic provided does not rule out the possibility that the number of interracial marriages has seen dramatic fluctuations over the years and this year is not the highest. Again, there is simply not enough information to understand fully the impact of the statistics. As a ...
We are interested in both the sample statistic and the population parameter in inferential statistics. In a later chapter, we will use the sample statistic to test the validity of the established population parameter.A variable, notated by capital letters such as XX and YY, is a charac...
What is H0 for a one-way ANOVA? If H0 is rejected, does that imply that each mean is significantly different from each other mean? Analysis of Variance The analysis of variance (ANOVA) is an inferential statistical procedure that ...

What is a T-Test? A T-Test is a hypothesis test that we use in statistics to compare two data sets’ respective means. It is a kind ofinferential statistics. It concludes if there is a significant difference between the two groups’ means, which otherwise could be related to a few ...
Inferential statistics are grounded in probability theory. Probability is a measure of chance, and underlying all statistical tests (either directly or indirectly) are probability calculations that assess the role of chance on the outcome of your analysis. Typically, with traditional (...
