Assignment 1
Answer 1.
As described in the question store summarized this data into single score by multiplying the number of responses by number assigned. With this procedure, they got mean value of 3.19. Which lies between the 3-unsure and 4-agree.
With which store manager will conclude that response is mild agreement or small unsure.
This is not correct interpretation of data. As this argument relies on assumption that psychological distance between agreement and strong agreement is same as in agreement and unsure. Which is not correct as the responses can also be distorted on psychological attitudes. To put it in simple terms Ordinal data cannot possess a mean value.

a). Gender Requires one of two responses – male or female
From this question, we will get Nominal data. Because it has two possible values male or female. We can count no. of males and females but both doesn’t have their actual values neither we can compare them to each other i.e. we can’t say that male has higher value than female. But we can say no. of males are less than or greater than no. of females.
b. Fahrenheit thermometers
Collects values representing temperatures in Fahrenheit
Collected values representing temperatures in Fahrenheit(F) is an Interval Data. As in the terms of temperature there is fixed interval. As difference between 1F and 3F is same as in 22F and 24F. However, we cannot say that 5F is half than 10F because there is no absolute zero in temperature. Temperature can increase to infinity as well as decrease to infinity in Fahrenheit.
c. Kelvin thermometers Collects values representing temperatures in Kelvin
Collected values representing temperature in kelvin(k) is a Ratio Data. Because in terms of kelvin temperature there is fixed intervals and as well as absolute zero. As there is absolute zero in kelvin temperature we can say that 5 degrees is half hot as compared to 10 degrees.
d. The number of items a customer buys
In whole numbers
It is also a ratio Data because there can be a customer buying no item. So, there can be an absolute zero. Moreover, we can also say that 5 items are half of 10
1. By hand, compute the mean, median, and mode for the following set of 40 reading scores:
What is a ratio? What are the different ways of expressing the relationship of two amounts? What information does a ratio provide?
The design included a number of survey questions with varying number of choices. Most of the questions required the surveyed person to decide on scales of 1-3 or 1-4. This will allow those taking the survey to find where they fit, but will not determine if certain parameters are a little above the middle or greatly above the middle like question 4a which states has increased or has decreased – we wont know by how much or how impressive it might be.
The next set of questions consisted of statements where the participants needed to choose one response the best expressed the incident in which they agree or disagree he from one being strongly agree to five being strongly disagree. The first statement was "Officers protect the community." The outcome was 23.6% of the individuals strongly agreed 21.8% agreed. There were 38.2% of the participants who were unsure, 7.3% of the participants who disagree and 9.1% who
4. Why is the curve between 1950 and 1980 relatively flat and centered around zero degrees difference from the baseline? (Hint: how is the temperature change being compared over time?)
(Strongly disagree = 1, Disagree = 2, Somewhat disagree = 3, Neutral = 4 Somewhat agree = 5, Agree = 6 and Strongly agree = 7). The lower the mean, the stronger the disagreement with the statement; and the higher the mean, the stronger the agreement with the statement). N = The total number of responses
Using the following rating scale, indicate the number that best indicates your agreement with the statement.
Description Positive attitudes Negative attitudes Strongly Agree (SA) 4.50 - 5 .00 1 Agree (A) 3.50 - 4.49 2 Undecided (U) 2.50 - 3.49 3 Disagree (D) 1.50 - 2.49 4 Strongly Disagree (SD) 1.00 – 1.49 5
For a majority of the statements, I have a firm opinion regarding a particular context about the subject: 17 mostly agree responses and 18 mostly disagree responses.
The ratio measurement has a ranking order, the distances between the numbers are equal, and it has an absolute zero. The length of stay was measured in minutes from the time of admission (absolute zero) to the time of discharge; like a timer.

Observations can have equal intervals and a zero in the scale. This type of measurement is different from the other measurement levels, due to the zero in the scale. Even though the properties are the like the interval level of measurement, because the points on the scale are equivalent. However, the zero on the scale is unique to the ratio measurement. This method effectively measures weight and count. These variables can be meaningfully added, subtracted, multiplied, divided A count variable ratio can determine how many clients a real estate agent had in 6 months. If the agent had zero clients It would meaningful to state that the agent had twice as many clients in the past six months and she had in the previous six months. Ratio scales provides the ultimate order, interval values, plus the ability to calculate ratios since a “true zero” can be
The financial data of company does not tell us the entire position of an organisation and its performance over the year or certain period of time for comparative purposes. Therefore, the use of ratios
Interpretation: According to 100 respondents of Maruti Suzuki 75 of them strongly agree that Sales person spent enough time with us in relation to true value car, 11 of them agree that Sales person spent enough time with us, 9 of them neither agree nor disagree that Sales person spent enough time with us, 5 of them disagree that Sales person spent enough time with us.
Using Ratio analysis, Charts and Graphs process the data to unable to draw effective inferences.
