Inferential statistics is concerned with making predictions or inferences about a population from observations and analyses of a sample. That is, we can take the results of an analysis using a sample and can generalize it to the larger population that the sample represents. In order to do this, however, it is imperative that the sample is representative of the group to which it is being generalized.

Is standard deviation a inferential statistic?
yes
Is correlation coefficient an inferential statistic?
yes
What are the advantages and disadvantages of inferential statistics?
One advantage of inferential statistics is that large predictions can be made from small data sets. However, if the sample is not representative of the population then the predictions will be incorrect.
What is inferential data?
There is no inferential data. There is inferential statistics which from samples, you infer or draw a conclusion about the population. Hypothesis testing is an example of inferential statistics.
When should inferential statistics typically be used?
Inferential statistics uses data from a small group to make generalizations or inferences about a larger group of people. Inferential statistics should be used with "inferences".
Is a t-test a descriptive statistic?
A t-test is a inferential statistic. Other inferential statistics are confidence interval, margin of error, and ANOVA. An inferential statistic infers something about a population. A descriptive statistic describes a population. Descriptive statistics include percentages, means, variance, and regression.
Is standard deviation a inferential statistic?
yes
Is correlation coefficient an inferential statistic?
yes

Differentiate inferential statistic and descriptive statistic?
y=a+bx+e sample regression model differentiate between y bar and E(Y)?
The process of using sample statistics to draw conclusions about true population parameters is called?
inferential statistic
What are the example of inferential statistics?
Mean, variance, t-statistic, z-score, chi-squared statistic, F-statistic, Mann-Whitney U, Wilcoxon W, Pearson's correlation and so on.
What is inferential data?
There is no inferential data. There is inferential statistics which from samples, you infer or draw a conclusion about the population. Hypothesis testing is an example of inferential statistics.
What is an inferrential statistic?
Inferential statistics is the part of statistics where we use sample data to try and infer (hence the name) what is happening in the population.
What is ANOVA related to statistics?
ANOVA is an inferential statistic used to test if 3 or more population means are equal or to test the affects of interactions.
What are examples of the relationship between descriptive and inferential statistics?
Descriptive statistics summarize and present data, while inferential statistics use sample data to make conclusions about a population. For example, mean and standard deviation are descriptive statistics that describe a dataset, while a t-test is an inferential statistic used to compare means of two groups and make inferences about the population.
