Which of these should be used as a way to make an educated guess about the relationship between?
inferential statistics
Why do you think is probability used as basis for inferential statistics?
Inferential statistics are used in situations where it can be assumed that random behaviour(s), subject to the mathematical laws of probability, must be taken into account.
Do inferential statistics provide descriptive information about a distribution of scores?
Not necessarily. Inferential statistics are statistics which are used in making inferences about some distribution. The only requirement is that they are based only on the set of observed values.
Techniques used to determine something about a population based on a sample?
Inferential statistics
Why inferential statistics is not required in census?
Inferential statistics is not required in a census because a census aims to collect data from every individual in a population, leaving no room for sampling error or uncertainty. The goal of a census is to provide an accurate count or measurement of a specific characteristic within a population, making the need for statistical inference unnecessary. In contrast, inferential statistics is used when data is collected from a sample of a population, and the goal is to make predictions or inferences about the larger population based on that sample.

inferential statistics
Compare and contrast descriptive statistics and inferential statistics?
Descriptive statistics are meant to describe the situation such as the average or the range. Inferential statistics is used to differentiate between a couple of groups.
What is inferential statistics?
Inferential statistics, is used to make claims about the populations that give rise to the data we collect. This requires that we go beyond the data available to us. Consequently, the claims we make about populations are always subject to error; hence the term "inferential statistics" and not deductive statistics.

What should be used as a way to make an educated guess about the relationship between the independent variable and the dependent variable?
Inferential Statistics
What type of statistics employ the use of sample data that is used to infer information about the population?
Inferential statistics.

Inferential statistics
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.

What are the Tools used in inferential statistics?
In general in Descriptive Statistics we use tools like central tendency, dispersion, skew, kurtosis to summarize a given set of data. But inferential statistics is much boarder than it. In inferential l statistics we use tools like chi square test, ANOVA, ACOVA, Correlation, Regression, Factor Analysis etc to predict the behavior based on the sample data.
Your teacher presented the distribution of grades on the last quiz. What type of statistics did she use to convey this information descriptive statistics or Inferential statistics?
Descriptive statistics. Descriptive statistics are used to summarize and present data in an informative way, providing characteristics of the data set such as mean, median, mode, and standard deviation. Inferential statistics, on the other hand, are used to make inferences or predictions about a population based on sample data.
