2. What assumptions about the data should be satisfied for a DA? What types of data screening should be performed to assess whether assumptions are violated?
Homework Answers
Answer)
DA or a Data Administrator is the profession where the person is
responsible for the requirements gathering, analysis, and design of
the database and they establish the flow of the data around the
organization and also between the databases and another system in
the organization. The assumptions about the data which should be
satisfied for a DA ca be that:
a) Standards are specified or can be specified across the
databases.
b) Establishing the policies and established policies regarding the
data usage, security, authorization, and data flow
c) Being able to assist in the development process of the
application using the data
d) Supporting the sharing of data across the levels and departments
of the company through a structured and common format manner.
There are many types of screening which should be performed to
assess that the assumptions stay intact and are the data is useful
as expected such as:
a) Data should be correct inside the database.
b) The DBMS software and system should be working and installed and
configured.
c) Data can be used from the DBMS to be used in the implementation
of information systems.
d) The database is tuned for optimal performance and is
efficient.
e) Data integrity is maintained and backups are made regularly.

Question 1: Each of the scenarios below represent situations in which (1) either all necessary assumptions for the unbiasedness of OLS estimators ("unbiasedness assumptions") are satisfied, or (2) one of the unbiasedness assumptions is violated. Look at the econometric model put forward in each scenario. For each scenario, state your opinion of whether or not all the unbiasedness assumptions are satisfied. If one assumption is violated, state which one does not hold true. Provide a brief explanation (no more than...

(4 points) Residuals vs fitted plots can be used to assess whether the four key assumptions for a simple linear regression have been met. Each of the plots below displays an instance where at least one of these assumptions may not have been met. For each plot, identify which assumption has been most violated, if any. 1. Plot A shows that A. The relationship between x and y cannot be assumed to be linear. B. The residuals do not appear...

Preliminary data analyses indicate that the assumptions for using pooled t-procedures are satisfied. Independent random samples of 103 plots with cropland and 99 plots with grassland yielded the given summary statistics for the number of species of bird. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean number of species in the two regions? Cropland Grassland x overbar 1 equals 14.12 x overbar 2 equals 15.87 s 1 equals...

Preliminary data analyses indicate that the assumptions for using pooled t-procedures are satisfied. Independent random samples of 102 plots with cropland and 100 plots with grassland yielded the given summary statistics for the number of species of bird. At the 1% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean number of species in the two regions? Cropland Grassland x overbar 1 = 14.51 x overbar 2 = 15.33 s 1 =...

Preliminary data analyses indicate that you can reasonably consider the assumptions for using pooled t-procedures satisfied. Independent random samples of 103 plots with cropland and 99 plots with grassland yielded the given summary statistics for the number of native species. Cropland: x bar 1= 14.62 s1=4.74 n1=103 Grassland: x bar 2= 15.89 s2=4.91 n2=99 The 98% confidence interval is from ? to ?
