Explain why two variables must both be quantitative in order to find the correlation between them

Mathematics

Butoxors [25]2 years ago

If the variables are not quantitative we cannot do the arithmetic required in the formulas for r.

<h3>What is a variable?</h3>
  • A variable in mathematics is a symbol and placeholder for a changing quantity or any mathematical object.
  • A variable can specifically represent a number, a vector, a matrix, a function, a function's argument, a set, or an element of a set.

Quantitative order:

  • Quantitative methods emphasize objective measurements and statistical, mathematical, or numerical analysis of data gathered through polls, questionnaires, and surveys, as well as by manipulating pre-existing statistical data using computational techniques.
  • Ordinal-level measurement data can be quantitative or qualitative.
  • They can be arranged in ranked order, but differences between entries are meaningless.
  • Measurement data at the interval level are quantitative.
  • They can be arranged in any order, and meaningful differences between data entries can be calculated.
  • We can't do the arithmetic required in the r formulas if the variables aren't quantitative.

Therefore, if the variables are not quantitative we cannot do the arithmetic required in the formulas for r.

Tyler believes that an 8-sided die can be used to predict whether customers at his store will use a coupon when making their pur
Alik [6]
"1 indicating a coupon and all other outcomes indicating no coupon"
Probability is (number of successful outcomes) / (number of possible outcomes)

Theoretical Probability of rolling a 1: 1/8 

Experimental Probability of using coupons: 4/48  =  1/12

So, the experimental probability of a customer using a coupon (that is, 1/12) is smaller than the theoretical probability of rolling a 1 (that is, 1/8).

The table below shows the typical hours worked by employees at a company. A salaried employee makes $67,000 per year. Hourly emp
nadezda [96]
First, we must calculate the weekly pay of an employee that is paid a fixed amount. Given that there are 52 weeks in a year, the weekly pay for a regularly paid employee is: 67,000 / 52 = $1,288.46 Now, we calculate the number of hours an employee that is paid hourly works per week: 0 + 10 + 8 + 8 + 7 + 6.5 + 4.5 = 44 So this employee is paid: 25 x 40 + 37.5 x 4 = $1,150 Therefore, it is recommended that a new employee goes for the salaried pay since the weekly earnings are greater in this option. The answer is C<span>.</span>
