Inferential and Descriptive Statistics

What is the purpose of statistical hypothesis testing in biology?

• To study the behavior of insects in a controlled environment

• To determine if there is a significant difference or relationship between variables in biological phenomena.

• To calculate the average weight of mammals

• To determine the color of a specific species of bird

What is the importance of statistical analysis in biology?

• Statistical analysis in biology helps in making sense of complex biological data, identifying patterns, testing hypotheses, and making informed conclusions.

• Statistical analysis in biology is only used for basic calculations

• Statistical analysis in biology only adds complexity to the data

• Statistical analysis in biology has no importance

What are the two different types of statistical analysis used in biology?

• Experimental and Observational Statistics

• Predictive and Causal Statistics

• Qualitative and Quantitative Statistics

• Descriptive and Inferential Statistics

How does statistical analysis help in drawing conclusions in biological research?

• By conducting experiments and making observations

• By using anecdotal evidence and personal experiences

• By guessing and making assumptions

• By analyzing data, identifying patterns, and determining the significance of results.

Which represents a descriptive statistics with a biological example?

• average height of a population of trees in a forest.

• median age of a population of rocks.

• significant difference in growth between two types of plants

• the number of legs in a population of animals.

What is the difference between inferential and descriptive statistics in biology?

• Inferential statistics focuses on summarizing data, while descriptive statistics involves making predictions about a population

• Descriptive statistics is used for drawing conclusions from a sample, while inferential statistics describes the characteristics of a dataset

• Inferential statistics is used to describe the characteristics of a dataset, while descriptive statistics involves making predictions about a population

• Inferential statistics involves making inferences and predictions about a population based on a sample, while descriptive statistics focuses on summarizing and describing the characteristics of a dataset.

How are inferential statistics used to make predictions in biological research?

• By analyzing data from a sample and making predictions about the larger population.

• By making predictions without analyzing any data

• By ignoring the sample data

• By using only qualitative data

From a past study from the American Dental Association it was found that 92% of Adults age 20-65 have suffered from at least one cavity.

• Descriptive

• Inferential

Between a Population and Sample: which size is bigger ?

• Population

• Sample

• Both can be the same

• Not enough information

The "p" in p-value stand for:

• Population

• Probability

• Popularity
