It can be important to be precise! Data can help cut through misinformation, but only if we are careful with our language and our numbers. Many are talking about Hydroxychloroquine as a “cure” for COVID-19, when in fact it is only being tested to help stop the spread of the virus after a known exposure. Thankfully, data can help us answer whether or not it is actually doing this.

The Chi-Square Goodness of Fit test is often the gateway to inferential statistics in high school. It appears in both the AP Biology and AP Statistics curricula and is one of the few statistical tests for which the test statistic can be easily calculated by hand even for datasets with a large number of samples.

Molecules are constantly in motion as a result of a cell's stored kinetic energy, which causes them to bump into each other and move in random new directions. Diffusion is the movement of molecules from an area of where there are many (high concentration) to an area where there are fewer (low concentration).

Does the environment in which a bee was raised determine its aggressiveness?
Honey bees are highly social creatures that live in large colonies of about 40,000 individuals and one queen. Every member of the hive works together to benefit the colony. Some of the tasks adult bees perform include making honey, nursing young, foraging for food, building honeycomb structures, and defending the colony.

When Charles Darwin talked about the “struggle for existence” he was making the observation that many individuals in the wild don’t survive long enough to reach adulthood. Many die before they have the chance to reproduce and pass on their genes to the next generation.

In what ways does the abundance and/or sex ratio of male and female humpback whales change over the course of the year in the Western Antarctic Peninsula? People have hunted whales for over 5,000 years for their meat, oil, and blubber. In the 19th and 20th centuries, pressures on whales got even more intense as technology improved and the demand for whale products increased.

How do female juncos determine the quality of potential mates?
Animals collect information about each other and the rest of the world using multiple senses, including sight, sound, and smell. They use this information to decide what to eat, where to live, and who to pick as a mate. Choosing a mate is an important decision that requires a lot of information, such as how healthy a potential partner is, and information about their genes. Mate quality can affect how many offspring an animal has and if their genes will get passed on to the next generation.

Do insects prefer local or foreign foods? Featured scientist: Elizabeth Schultheis from Michigan State University Research Background: Insects that feed on plants, called herbivores, can have big effects on how plants grow. Herbivory can change the size and shape of plants, the number of flowers and seeds, and even which plant species can survive in a habitat.

When the tragedy of a mass shooting repeats itself in cities across the United States, we find ourselves asking why it happens. While gun violence is not a uniquely American problem, more mass shootings occur in the United States than in any other country on earth. And they keep happening. What can explain this? Data can provide insights into the underlying factors that may be responsible for gun violence in the United States.

Since it can be difficult and time consuming to observe wild mammals, researchers use camera traps to record data on the populations of interest. Camera traps are motion-activated cameras that photograph any animal that passes in front of the camera. The photos are then reviewed to identify which species were captured on camera and how frequently they were recorded in the photos. These data can then be used to answer research questions about biodiversity in the surrounding area and inform the Maijuna’s conservation management plan.
