How do you calculate absolute frequencies?
Absolute frequencies are calculated by first identifying intervals based on your data and then identifying the number of values within your data set that lie within these interval. Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
What is the difference between frequency distribution and relative frequency distribution?
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
When do you use the relative standard deviation instead of standard deviation?
Use %RSD when comparing the deviation for popolations with different means. Use SD to compare data with the same mean.
When would you choose a bar graph to present data?
when i am comparing data
What kind of data could be used to map the relative position of three genes on a chromosome?
The data that could be used to map the relative position of three genes on a chromosome are crossover frequencies in genetic crosses. By comparing the frequency of recombination events between the genes, you can infer their relative distances on the chromosome. Closer genes will have fewer crossovers, while genes further apart will have more crossovers.

Why low frequencies are not used for data transmission in computer networks?
Low frequencies are avoided for data transmission in computer networks to prevent data loss due to attenuation of the signal. Also, low frequencies are incapable of transferring data at the speeds of higher frequencies.
What are wide and narrow band frequencies?
Wideband frequencies refer to a range of frequencies used for transmitting data at high speeds, while narrowband frequencies cover a smaller range of frequencies and are used for transmitting data at slower speeds. Wideband frequencies are ideal for applications requiring large amounts of data to be transmitted quickly, such as video streaming, while narrowband frequencies are suitable for applications with lower data requirements, like voice calls.

What is transmission bandwidth?
The frequencies which are used to transmit data.
What is the difference between the goodness of fit test and the contingency test?
Goodness of fit test is used to test a single population. The null hypothesis will be that the observed frequencies are equal to expected frequencies (based on computed intrinsic values given the extrinsic values). A good example would be comparing observed phenotype frequencies against expected frequencies calculated from the parental genotypes (Simple dominance gives rise to 1:2:1 ratio with two parental heterozygotes). Contingency test is used to see whether or not different populations are associated. The null hypothesis will be that that different populations are independent of one another. A good example would be comparing the effect of different host plants on different populations of insects. (Effect of Host A on Insect population 1, 2, 3; Effect of Host B on Insect population 1, 2, 3; etc)
Why bar graphs are useful for comparing data?
bar graphs are useful for comparing data b/c you cn actually see what the difference is between them.
What kind of data would you record in a bar graph?
You use it when you are comparing data.
