When should one use a t-test instead of a chi-square test for statistical analysis?

A t-test is used when comparing means of two groups, while a chi-square test is used for comparing frequencies or proportions of categorical data. Use a t-test when comparing numerical data and a chi-square test when comparing categorical 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.


When should one use the chi-square test instead of the t-test?

The chi-square test should be used instead of the t-test when analyzing categorical data or comparing frequencies of different categories, while the t-test is used for comparing means of continuous data.


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.


When should one use a chi-square test instead of a t-test for statistical analysis?

A chi-square test is used when analyzing categorical data, such as comparing proportions or frequencies between groups. On the other hand, a t-test is used when comparing means between two groups. So, use a chi-square test when dealing with categorical data and a t-test when comparing means.


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.


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 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.
