If densities are equal, a highly dispersed population will yield higher variance in number of individuals per quadrant. This is so because number of people living in different quadrants will vary highly in case of dispersed population. Dispersed population is more spread and hence possesses higher variance.
You can also think of it graphically. Aggregated population stays close enough to each other and hence will have lower variance.
If densities are equal, which would yield a higher variance in numbers of individuals per quadrant:...

A war that lowers its population by one-half. d. None of the above. 2/ The Harrod-Domar model predicts that investment will lead to permanently higher growth of income per capita.

Which of the following would provide a higher cost per unit? A. Weighted average would always provide a higher cost per unit because it includes all costs to date. B. FIFO would always result in a higher cost per unit because it only includes the costs from this period. C. FIFO would result in a higher cost per unit in times of rising prices. D. FIFO would result ion a higher cost per unit in times of decreasing prices.
A research study concluded that self-employed individuals do not experience higher job satisfaction than individuals who are not self-employed. In this study, job satisfaction is measured using 18 items, each of which is rated using a Likert-type scale with 1–5 response options ranging from strong agreement to strong disagreement. A higher score on this scale indicates a higher degree of job satisfaction. The sum of the ratings for the 18 items, ranging from 18–90, is used as the measure of...

Which of the following statements is CORRECT? A bond's current yield must always be either equal to its yield to maturity or between its yield to maturity and its coupon rate. If a bond sells at par, then its current yield will be less than its yield to maturity. If a bond sells for less than par, then its yield to maturity is less than its coupon rate. A discount bond's price declines each year until it matures, when its...
dN dt (K-N) The change in population size (dN) per unit time (d),--, is equal to rN. What would be the population change per year (eg, dt = 1 yr) in a population of 5433 individuals, with a per capita growth rate of 0.06, and a carrying capacity of 7606?
Assume that a population of tuna is at K. To provide maximum sustainable yield, how would you recommend that fishermen should harvest this population, and why? A. Harvest down to maximum sustainable yield (where the slope of the growth curve is the smallest); this allows the population to be renewed the fastest because it has the maximum per capita growth rate. B. Take one small harvest then allow the population to recover quickly; this minimizes the number of individuals removed...

There are two types of potential borrowers in equal numbers among the population. All haveprojects that require an investment of $100, which must be borrowed. Type A projects yield agross return of $130 in one year with probability .8; they fail and yield 0 with probability .2. Type B projects yield a gross rate of return of $250 with probability.4, but fail, yielding zero,with probability .6. Potential lenders require an expected gross return of $102 on $100 loaned. With symmetricinformation,...
