How hard is it to get a 3 on AP stats? ›

Only 60% of students who take the AP Statistics exam score a 3 or above, which puts it just outside of the top 10 hardest AP classes (in terms of the numbers, Physics 1 is the most difficult AP class, with just 42% of students scoring a 3 or above on the exam.

Final answer:

To estimate the size of a typical housing unit in a certain town, a sociologist can use a cluster sampling method by randomly selecting nonoverlapping regions and selecting all housing units within those regions.

When random selection is used in an observational study, we can generalize results from the sample to the larger population with confidence. Without random selection, our ability to generalize is limited.

Then, you select a random sample from each stratum, proportional to its size in the population. The advantage of stratified sampling is that it ensures that each stratum is adequately represented in the sample, and reduces the sampling error and variability within each group.

As a general guide, though, you can consider roughly more than 70% correct as being in the 5 range, 50-69% for a score of 4, 40-49% for a score of 3, 30-39% for a 2, and below 30% would likely be a 1. Again, these ranges are approximations and can vary by subject and by year.

Credits are earned by scoring 5 on a minimum of four AP tests. Certain AP examinations test material covered in one semester only, and for each of these, Harvard confers only one half credit toward Advanced Standing. For more information, visit Harvard's website.

The final condition relates to action by the agents. Called social control, it is the only way to end the collective behavior episode (Smelser 1962).

Why do we have two words for a big city: metropolis and megalopolis? A metropolis is just one city while a megalopolis includes many different cities.

At the societal level, sociology examines and explains matters like crime and law, poverty and wealth, prejudice and discrimination, schools and education, business firms, urban community, and social movements.

What is a matched-pairs design example? One example would be a study of 100 people for a diet. Each subject would be paired with another subject with similar age and weight. Then the pairs would be placed into the study groups such that each subject is in an opposing study group, diet or no diet.

How to conduct simple random sampling? ›

To create a simple random sample, there are six steps: (a) defining the population; (b) choosing your sample size; (c) listing the population; (d) assigning numbers to the units; (e) finding random numbers; and (f) selecting your sample.

Disadvantages of using a stratified random sample include: It can be difficult and time-consuming to select relevant strata groups for your research study. It can require more time to analyze stratified data than it would take to analyze data that has not been categorized into groups.

When using stratified sampling, you create subgroups based on certain characteristics of your population, such as age, gender, income, or education level. This ensures that each subgroup is a fair representation of the entire population, and that your sample is not biased towards any particular characteristic.

In short, it ensures each subgroup within the population receives proper representation within the sample. As a result, stratified random sampling provides better coverage of the population since the researchers have control over the subgroups to ensure all of them are represented in the sampling.

While AP Statistics is not the easiest AP class, it is also not the most difficult. In fact, when compared to other AP math classes, like Calculus AB and BC, AP Statistics is often considered the easier option.

But what is a passing AP score? The College Board considers a score of 3 or higher a passing grade. That said, some colleges require a 4 or 5 to award credit. Whether a 3 is a good AP score depends on the colleges you're applying to.

Of those, 55.7% of students scored a 3 or higher and 31.5% scored a 4 or higher. This might come as no surprise given how students are required to demonstrate a high-level of analytical, argumentative, evaluative and persuasive writing.

Colleges are generally looking for a 4 (“well-qualified”) or 5 (“extremely qualified”) on the AP exam, but some may grant credit for a 3 (“qualified”). These scores mean you have proven yourself capable of doing the work in an introductory-level college course.
