What is the difference between dependent and independent samples?

Dependent samples occur when you have two samples that do affect one another. Independent samples occur when you have two samples that do not affect one another.

What is an example of dependent population?

The elderly population refers to people aged 65 and over and the youth population to people aged less than 15. The share of dependent population is calculated as the sum of the elderly and youth population expressed as a ratio of the total population.

What makes a sample independent?

Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Many statistical analyses are based on the assumption that samples are independent.

What is independent population?

Independent sample. The samples from two populations are independent if the samples selected from one of the populations has no relationship with the samples selected from the other population.

How do you know if something is independent or dependent?

In general, an event is deemed dependent if it provides information about another event. An event is deemed independent if it offers no information about other events.

How do you define dependent population?

Dependent population is defined as that part of the population that does not work and relies on others for the goods and services they consume.

What is the difference between the independent variable and a dependent variable?

The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

What are dependent samples?

Two samples are dependent(or consist of matched pairs) if the members of one sample can be used to determine the members of the other sample. Tricks: The words like dependent, repeated, before and after, matched pairs, paired and so on are hints for dependent samples.

How do you know if data is independent?

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.

Who are called the active and dependent population?

(i)Persons who no longer contribute directly to an economic activity constitute dependent population. (ii) These persons are also called non-workers. (iii)Generally persons above 60 years and children below 15 years belong to this group. (iv)These persons depend upon workers for their living.

What is the difference between dependent and independent samples explain the concept of comparing two means in both dependent and independent samples?

Dependent samples are paired measurements for one set of items. Independent samples are measurements made on two different sets of items. When you conduct a hypothesis test using two random samples, you must choose the type of test based on whether the samples are dependent or independent.
