inferential statistics
Inferential statistical methods are used when data is collected from a sample in the population. Inferential statistics are used to generalize the results of the sample to the population. In a census you have data from each and every member of the population, so you just use descriptive 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.
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.

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.

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.

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.
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.
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.
