Fill in the bank for the following given the scenario that we have measured the pulse rate value of a sample with the variables of gender, ethnic group (4 groups), marital status (5 categories),age and weight. What statically test of significance should be used for finding if : pulse rate average is different when measured across Bach of 4 months for the same sample pulse rate can be predict fed by age pulse rate average is higher for males than females pulse rate average a year later is different from the original average for the same people marital status is related to gender pulse rate value is predicted by age and height pulse rate average is different across ethnic group pulse rate is related to height there is an interaction between gender and ethnic group using pulse rate as the dependent measure pulse rate average for the sample is higher than 72

Solution

As there are multiple parts to the question, the first 4 will be answered:

1. For observing if the average is different across each of the 4 month for the same sample, we check the signficance of the coefficient of time variable, after defining a time series with unit of 1 month.

We can also use ANOVA with 1treatment and 4 levels (one for each month)

2. For this, we perform a simple linear regression and conduct a t-test on slope coefficient.

Answer:Regression of pulse rate on Age and t-test of slope coefficient = 0

3. For this, we use 2 sample independent t-test, to see if the average of males is equal to that of females.

4. For this,we check the signficance of the coefficient of time variable, after defining a time series with unit of 1 year.

We can also perform a t-test to check if the mean of the data is equal to the original avergae.
