Answer:
Weinstein, McDermott, and Roediger (2010) conducted an experiment to evaluate the effectiveness of different study strategies.
One part of the study asked students to prepare for a test by reading a passage.
In one condition, students generated and answered questions after reading the passage.
In a second condition, students simply read the passage a second time.
All students were then given a test on the passage material and the researchers recorded the number of correct answers.
a. Identify the dependent variable for this study:
The dependent variable for this study is effectiveness.
b. Is the dependent variable discrete or continuous?
The dependent variable is discrete.
c. What scale of measurement (nominal, ordinal, interval, or ratio) is used to measure the dependent variable?
The scale of measurement is ratio scale.
Step-by-step explanation:
a) To identify the dependent variable you need to find the item, circumstance, concept, sense, time frame, or any category in an specific scientific research, that is going to be measured. In this particular case, the dependent variable measured is the effectiveness of the different study strategies used based by the number of correct answers on a test. This variable could be influenced by independent variables also.
b) The method by which we obtain the resulting values make the difference between a discrete variable and a continuous variable. If measuring is the used method, then it is a continuous variable, but if counting is the utilized method to get the correct number of correct answers, as it is stated in this case, then it is a discrete, finite and countable.
c) The measurements´ accuracy are given by the different scales or levels and they are classified as:
- Nominal
- Ordinal
- Interval
- Ratio
Interval and ratio scales data are similiar is also known as called metric, sharing units, and represent quantiy., therefore the scale of measurement used in this study is ratio scale.
Sn = −728
Sn = 2,186
Sn = 728
The sum of a geometric series is calculated using the relevant formula from a1, r, and an. The unknown n can be calculated from the given an, a1 and r. These are then substituted into the sum formula.
The given is a geometric series where first term a1 = -2, common ratio r = 3, and last term an = -1458. The sum of a geometric series, Sn, can be calculated using the formula , where n is the number of terms in the series. However, in this case, we don't know n directly, but we do know the nth term (an) using the formula , you can rearrange to solve for n: n = log((an/a1))/log(r) + 1. Plug this value of n and the given a1, r into the sum formula to get the sum.

$900 biweekly =
$650 weekly =
$700 semimonthly =
Answer:
The annual salary are $14400,$23400 ,$33800 , $16800
Step-by-step explanation:
Given : paycheck cost and its pay period .
We have to calculate the annual salary.
Consider
1) Paycheck amount = $ 1200
period = monthly
We know 1 year = 12 months
So annual salary = $1200 × 12 = $14400
2) Paycheck amount = $ 900
period = biweekly
We know 1 year = 52 weeks
since, payment is made biweekly so
number of payment made in 1 year is 26 times.
So annual salary = $900 × 26 = $23400
3) Paycheck amount = $ 650
period = weekly
We know 1 year = 52 weeks
So annual salary = $650 × 52= $33800
4) Paycheck amount = $ 700
period = semi monthly
We know 1 year = 12 months
since, payment is made semimonthly so
number of payment made in 1 year is 24 times
So annual salary = $700 × 24 = $16800
Thus, the annual salary are $14400, $23400, $33800, $16800
