Front

What does it mean when we say 50% of the data lies between two values?

Back

It means that half of the data points in a dataset fall within that range. This is often related to the concept of the median in statistics.

Front

What is the median of a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.

How do you find the high score in a set of data?

Back

The high score is the maximum value in the dataset. It can be found by identifying the largest number in the list of scores.

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, and maximum. It helps visualize the distribution and identify outliers.

Front

What does it mean if a distribution is skewed right?

Back

A right-skewed distribution has a longer tail on the right side. This means that most of the data points are concentrated on the left, with fewer high values stretching out to the right.

Front

What is the range of a dataset?

Back

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3) in a dataset. It measures the spread of the middle 50% of the data.

Front

What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data. It shows how many data points fall within specified ranges (bins).

Front

What is a skewed distribution?

Back

A skewed distribution is one that is not symmetrical. It can be skewed left (more data on the right) or skewed right (more data on the left).
