Front

How do you calculate the total number of measurements in a dataset?

Back

To calculate the total number of measurements, sum all the individual data points or counts.

Front

What is the significance of daily high temperatures in data analysis?

Back

Daily high temperatures are significant as they help in understanding weather patterns, trends, and comparisons between different locations.

Front

How can you determine which town is usually warmer based on temperature data?

Back

To determine which town is usually warmer, compare the average daily high temperatures over a specified period.

Front

What is the average of a set of numbers?

Front

What is the mode in a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

What is the median in a dataset?

Back

The median is the middle value when the numbers are arranged in order; if there is an even number of observations, it is the average of the two middle numbers.
