A teacher has asked all the students in the class which days of the week they get up after 8 a.m. Which of the following is the best way to display the frequency for each day of the week?

A. Pie graph

B. Bar graph

C. Histogram

D. Scatterplot

Answer Explanation:

The best way to display the frequency of each day of the week when students get up after 8 a.m. is by using a bar graph. Bar graphs are well-suited for representing categorical data, where each day of the week is a separate category, and the height of each bar corresponds to the count or frequency of students waking up late on that specific day.

Note: Histograms, on the other hand, are more appropriate for visualizing continuous or numerical data and are not ideal for categorical data like days of the week. Histograms are useful for understanding the distribution of data, identifying patterns, and assessing the shape of the data distribution, such as whether it's normally distributed, skewed, or has multiple modes.

As you can see below, the Histogram is used to depict a pattern/continuous data. While a bar graph does just fine even with discrete data.

Therefore, the Correct Answer is B.

  • Q #1: Which of the following is the mean of the set data below? 30, 29, 28, 30, 24, 12, 26, 33, 25, 23

    A. 30

    B. 21

    C. 27

    D. 26

    Answer Explanation

    The mean is the total divided by the number of elements in the data set. From the given data set:

    Total=30+29+28+30+24+12+26+33+25+23=260

    Number of items, N=10

    Mean=total/N=260/10=26

    The mean is 26.

  • Q #2: Using the numbers below, which of the following is the greatest? 4/3, 27/20, 1.369, 1.357  

    A. 1.369

    B. 4/3

    C. 27/20

    D. 1.357

    Answer Explanation

    to do a comparison of the given data set, we convert the fraction numbers into the approximate decimals.

    4/3=1.333

    2720=1.35

    Now, we have 1.333, 1.35, 1.369, 1.357. These numbers are arranged from the smallest to the largest number, we look at the number in the second decimal place value

    1.333 the number in second decimal place value is 3

    1.35 the number in third decimal place value is 5

    1.369 the number in third decimal place value is 6

    1.357 the number in third decimal place value is 5

    However, 1.35 and 1.357 have 5 in the second-place vale. We use the ird place value to compare the two number:

    1.35 is same as 1.350 and the number in the third-place value is 0

    1.357 the number in the third-place value is 7

    Now, 0 is less than 7, and thus 1.35 is less than 1.357

    Overall, 3 is less than 5, and 5 less than 6 and the provided numbers can be arranged from the smallest to the largest as:

    1.333, 1.35, 1.357, 1.369

    Thus, the corresponding given numbers organized from the smallest to the largest become:

    4/3, 27/20, 1.357, 1.369

    The greatest value is 1.369

  • Q #3: A patient drives 19 miles one way to a medical facility for treatment. How far does the patient drive round-trip in 22 days of treatment?

    A. 1,254 miles

    B. 1,672 miles

    C. 418 miles

    D. 836 miles

    Answer Explanation

     Round trip means to and from, which is twice the distance from home to a medical facility.

    In one day, the round trip=19+19=38 miles

    So, in 22 days, the round trip=38*22=836 miles.

    The patient will cover 836 miles in 22 days.
