Quantitative — Statistics & Data (الإحصاء) for the GAT (KSA) Exam — Texas candidates

10% of the GAT (KSA) test plan. Mean, median, mode, data interpretation, and probability in the GAT Quantitative section. Calibrated for Texan candidates.

Behind every published pass rate is a distribution of which topics caused most of the failures. This is one of those topics. Quantitative — Statistics & Data (الإحصاء) sits at roughly 10% of the General Aptitude Test — Saudi Arabia content distribution — Statistics and data interpretation account for a significant portion of GAT Quantitative questions. These include calculating mean, median, and mode from data sets, interpreting bar charts and pie charts, and basic probability. Data interpretation questions test the ability to extract information from tables and graphs quickly. Pass rates for the GAT (KSA) are published annually by the awarding body and vary by cohort and locale. For Texas candidates preparing for GAT (KSA), the calibration of study to local context matters: Texas is the second-largest CDL-issuing state and a top-3 state for NCLEX-RN candidates. TxDPS administers CDL skills tests; the Texas Board of Nursing recognises NCLEX results from Pearson VUE.

Pass rates for GAT (KSA) (Texas, USA) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Not sorting data before finding the median — median requires ordered data
  • !Confusing mean (average) with mode (most frequent) in word problems
  • !Reading graph scales incorrectly — especially when the y-axis does not start at zero

Study tips

  • 1Memorize the three central tendency formulas: mean = sum/n; median = middle value of ordered data; mode = most frequent.
  • 2For data interpretation, always read the chart title, axis labels, and units before attempting questions.
  • 3Practice probability with simple events: P(event) = favourable outcomes / total outcomes.
  • 4For CDL: book your skills test at a TxDPS megacenter (Houston, Dallas, San Antonio, Austin) or one of the 200+ third-party testers; megacenter wait times average 4–6 weeks.
  • 5For NCLEX-RN: the Texas Board of Nursing requires fingerprinting via IdentoGO before authorization-to-test (ATT) is issued — start that process the same day you submit your application.
  • 6Spanish-language CDL written tests are offered in Texas; the skills/road portion is conducted in English. Many CDL training programs in the Rio Grande Valley teach a bilingual track.

Sample GAT (KSA) Quantitative — Statistics & Data (الإحصاء) questions

These sample items mirror the format and difficulty of real GAT (KSA) questions. Practice with thousands more on the free Koydo question bank.

  1. 1

    The scores of 5 students are: 72, 85, 90, 78, 85. What is the mode?

    • A82
    • B85Correct
    • C78
    • D90
    Why this answer?

    Mode is the most frequently occurring value. In the data set {72, 85, 90, 78, 85}, the value 85 appears twice while all others appear once. The mode is 85.

  2. 2

    A bag contains 3 red, 5 blue, and 2 green balls. What is P(blue)?

    • A3/10
    • B1/2Correct
    • C2/10
    • D5/8
    Why this answer?

    Total balls = 3 + 5 + 2 = 10. P(blue) = 5/10 = 1/2. There are 5 blue balls out of 10 total.

Frequently asked questions

What data representation types appear in GAT statistics questions?
GAT statistics questions use: tables (frequency tables, cross-tabulation), bar charts, pie charts, and line graphs. Candidates must be able to read values from these representations and perform calculations (mean, percentage, ratio) based on the presented data.
What is the GAT (KSA) pass rate for Texan candidates?
Pass rates for GAT (KSA) candidates in Texas, USA are published periodically by the awarding body. Practice questions, full-length simulations, and weak-area drills are the highest-impact way to improve your odds.
How long should Texan candidates study Quantitative — Statistics & Data (الإحصاء) for the GAT (KSA)?
For most candidates, focused mastery of Quantitative — Statistics & Data (الإحصاء) requires 20–40 hours of deliberate practice — drilling sample questions, reviewing failure modes, and timing yourself against exam conditions. Texas is the second-largest CDL-issuing state and a top-3 state for NCLEX-RN candidates. TxDPS administers CDL skills tests; the Texas Board of Nursing recognises NCLEX results from Pearson VUE. Combine Quantitative — Statistics & Data (الإحصاء) study with full-length mock exams in the final two weeks before your test date.
