population mean

population standard deviation

Calculate the mean of the following data:

3,5,1,5,7,3,11,3,2,2,3,3,6

Calculate the median of the following data:

3,5,1,5,7,3,11,3,2,2,3,3,6

Calculate the IQR of the following data:

3,5,1,5,7,3,11,3,2,2,3,3,6

The mean of a sample is always equal to the mean of the population

Standard deviation can only be calculated for quantitative data

Interquartile range gives an idea of the total range of our data

Standard deviation is resistant to outliers

The median is extremely affected by outliers

Assume SAT scores are normally-distributed with mean 500 and standard deviation of 90. What is the probability of randomly choosing a student that scored between 410 and 680?

When our data is clearly skewed, the best measure of center to summarize the data is the median.

When designing an experiment, what 3 principles are necessary to make causal inference?

What is the key difference between an observational study and experimental design?

If I roll a six-side fair die and toss a coin at the same time, what is the theoretical probability that I toss a heads and an even number?

The sum of all probabilities for a given experiment must add up to 1 or -1

The population mean and standard deviation are most likely known when we analyze data.

Identify the outliers for the following data, if there are any:

3,2,3,2,4,3,3,2,2,2,0,2,2,4,5,7

The distribution of a random variable is the probability that that variable occurs
