Importance of data

1- The process of collecting data is called _________________

• a.data analysis

• b.data collection

• c.data visualization

2- Ahmed observed the soil, moisture, water, weather, and rainfall of the Date trees to take a decision on the best months to grow a Date tree.

In computer science, information and facts observed and collected are known as?

• Data

• Domain

• Desktop

3- This plot is ------------

• Bar graph

• Scatter plot

• Line plot

4- Using the sensors in weather stations, Ahmed collected the weather information for a complete year.

The bigger the data collection the better understanding Ahmed will have about the Date tree growth. Is this statement true or false?

• True

• False

5- Through data analysis, Ahmed found that during the first year of the Date tree growth, it required 20 – 25 litres of water twice a day. In data analysis, this relationship between the tree's growth and watering is referred to as?

• Collection

• Correlation

• Control

6- import matplotlib.pyplot as plt

import pandas as pd

grades = pd.DataFrame([[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],

[92, 89, 88, 85, 81, 78, 75, 75, 72, 65]])

plt.scatter(grades.loc[0, :], grades.loc[1, :], color="black")

plt.title("Grades and absences")

plt.xlabel("Absences")

plt.ylabel("Grades")

plt.show()

* The title of the graph is -----------

• Grades

• Absences

• Grades and absences

7- Using the data collected, Ahmed developed many graphs and plots to show to his supervisor. These graphs and plots have made Ahmed’s supervisor understand his data analysis quicker and clearer.In computer science, what is this process of data representation called?

• Data Process

• Data Visualization

• Data Requirement

8- This plot is ----------
