Desmos Statistical Functions Overview

This video tutorial demonstrates how to use Desmos to calculate common statistical measures such as mean, median, min, max, quartiles, and standard deviations. It explains how to input data into Desmos, create lists, and utilize various statistical functions. The video also discusses different methods for calculating quartiles and highlights the importance of understanding these methods.

Which function in Desmos provides the sum of all data elements?

• length

• total

• median

• mean

What is the purpose of the 'length' function in Desmos?

• To determine the median

• To find the sum of data

• To count the number of data elements

• To calculate the average

How can you find the mean of a dataset in Desmos?

• Using the 'median' function

• Using the 'mean' function

• Using the 'min' function

• Using the 'total' function

If the data is already ordered, what can be easily identified?

• Standard deviation

• Quartiles

• Min and max

• Mean and median

Which function is used to find the first and third quartiles in Desmos?

• total

• stdev

• quartile

• quantile

What is the difference between 'stdev' and 'st devp' in Desmos?

• 'stdev' is for population, 'st devp' is for sample

• 'stdev' is for sample, 'st devp' is for population

• Both are for sample

• Both are for population

How is the range of a dataset calculated?

• Max plus min

• Max minus min

• Mean minus median

• Sum divided by count

What method does Desmos use for determining quartiles when there is an odd number of data values?

• Exclusive method

• Average method

• Inclusive method

• Median method

In the exclusive method, what is not included in the upper and lower halves of the data?

• Mean

• Range

• Median

• Mode

What is the result of the range calculation if the max is 98 and the min is 65?

• 65

• 98

• 33

• 63
