If the frequency is 3 what is the cumulative frequency?
It is 3 more than the cumulative frequency up to the previous class or value.
Frequency and cumultive frequency are two types of?
Data representation. Cumulative frequency is the sum of all previous frequencies.
How the total builds as each number is added to previous ones is shown by?
The cumulative sum.
Why does a cumulative frequency graph never go down?
Because of the word "cumulative". What that means is that the height of the graph for any value (X=x) is the number (or proportion) of observations that were less than or equal to the value x. Now consider the cumulative value of the graph for a value of X which is bigger than x. All the previous observations were ≤ x and so they will be ≤ the newer, larger value. So the height of the cumulative graph cannot decrease. It may increase if there are any observations whose value was between x and the new value.
How do you calculate mid year population?
previous population+birth-death
How do you spell previous?
That is the correct spelling of "previous" (prior, earlier, immediately before).
What does cumulative mean?
Incorporating all data up to the present; That is formed by accumulation of successive additions; Think of it like a running total. If you have totalled up a set of numbers (eg scores), and then add one more number to it, the cumulative score is the combined sum of the previous total plus the additional number added to it.
What does SP 3 mean?
Service Pack 3. A service pack is a cumulative update of all of the security and bug fixes since the previous service pack, put sometimes new functionality.
What was the leap year before 1972?
The leap year immediately previous to 1934 would have been 1932.
What was the population of Brazil in 1893?
In the 1890 census the population was 14,333,915. The previous census was in 1872, where the population was 9 930 478. By 1900 the population had risen to 17,438,434, a 21.7% increase.
How does genetic drift lead to a change in a populations gene pool?
Genetic drift reduces variation in a population through allele loss, there are 2 situations of GD: a) Bottleneck effect: number of individuals is reduced significantly by a random event b) Founder effect: few individuals are separated and establish their own population both situations result in different allele frequency representations in new populations from their previous population`s
What causes an allele frequency to go up in one generation and back down in the next generation?
There are three basic reasons: 1. Natural Selection-- thr environment may have favored the allele in previous generations, but now disfavors it. 2. Genetic Drift-- in every finite population, the frequency of an allele will fluctuate due to chance. For example, the vast majority of sperm fail to fertlize any egg, so allels can be lost this way due to chance. Individuals carrying a copy or copies of an allele may die young due to random accidents, or may never find a mate. These basic chance events cause the frequencies of alleles to fluctuate, and the degree of frequency change depends upon the population size. The greater the population size, the smaller the change in frequency. 3. A combination of both.
